I literally sit in math class for 90 minutes confused every second. I go to RU-vid, search up what I need to understand, and know exactly what to do in 10 or less minutes. Thank you for your help..
GUYS: (for the table of values) The zeroes (x-intercepts) are when Y = 0, not when X = 0 SO for example in the eqn. y= 1/2 (x+4) (x-6) you make an x y table of values from -4 to 6, plugging in those values into the eqn. for X Then, the y-intercept is revealed as well (0,-12) and the zeros are (-4,0) (6,0) Another way to do it without subbing in the -4 to 6 values: sub in x = 0 y = 1/2 (0+4) (0-6) y= -12 and y=0 1/2 (x+4) (x-6) x = -4 or x = 6
I wish that you were my teacher. Because my teacher just shows us power points about math and she only talks to the smart people that have good grades and no the people with worst grade in the class and I'm like gg I'm going to fail math
very helpful! But I think you overcomplicated finding the zeros. You just have to look in the brackets (x-s)(x-t) and the intercepts will be (s,0) and (t,0) but with opposite symbols
At 4:18 you say that the x value for the vertex needs to be two away from each x intercept point, which should be four since theres a gap of eight between minus two and six ;-)
I teach this by showing students that a parabola is a curve where two straight lines are multiplied together. Hence what is shown as (1/2) *( x--6)(x-+2) = y y1= (x-6) is one straight line and (x+2) =y2 is another straight line and the zeros are clearly seen. Multiplying these shifted straight lines will give the full range of the parabola note that + * + = + and -- * -- = + hence both horns of the parabola extend up and out. other higher orders can be looked upon as y= (x -a)(x-b)(x-c)(x-d)(x-e) and the products of these straight lines can give the cubic etc orders . Plotting straight lines and multiplying them is a good way of looking after " quadratics "
Ever on and on, I continue circling With nothing but my hate and the carousel of agony Till slowly I forget and my heart starts vanishing And suddenly I see that I can't break free, I'm Slipping through the cracks of a dark eternity With nothing but my pain and the paralyzing agony To tell me who I am! Who I was! Uncertainty enveloping my mind Till I can't break free and Maybe it's a dream, maybe nothing else is real But it wouldn't mean a thing if I told you how I feel So I'm tired of all the pain, all the misery inside And I wish I could live feeling nothing but the night You could tell me what to say, you could tell me where to go But I doubt that I would care, and my heart would never know If I make another move, there'll be no more turning back Because everything would change, and it all would fade to black Will tomorrow ever come? Will I make it through the night? Will there ever be a place for the broken in the light? Am I hurting? Am I sad? Should I stay or should I go? I've forgotten how to tell, did I ever even know? Can I take another step? I've done everything I can All the people that I see, they will never understand If I find a way to change, if I step into the light Then I'll never be the same and it all will fade to white Ever on and on, I continue circling With nothing but my hate and the carousel of agony Till slowly I forget and my heart starts vanishing And suddenly I see that I can't break free, I'm Slipping through the cracks of a dark eternity With nothing but my pain and the paralyzing agony To tell me who I am! Who I was! Uncertainty enveloping my mind Till I can't break free and Maybe it's a dream, maybe nothing else is real But it wouldn't mean a thing if I told you how I feel So I'm tired of all the pain, all the misery inside And I wish I could live feeling nothing but the night You could tell me what to say, you could tell me where to go But I doubt that I would care, and my heart would never know If I make another move, there'll be no more turning back Because everything would change, and it all would fade to black If I make another move, if I take another step Then it all would fall apart There'd be nothing of me left If I'm crying in the wind, if I'm crying in the night Will there ever be a way? Will my heart return to white? Can you tell me who you are? Can you tell me where I am? I've forgotten how to see I've forgotten if I can If I opened up my eyes, there'd be no more going back 'Cause I'd throw it all away, and it all would fade to black
it was that simple...? boi my teachers actually good this year, i guess i got too distracted since i was pretty upset of my test grade bc i missed a day where we learned a lot messing up my test score
idk if this helps but in the equation y=a(x-p)(x-q) the p and q are the two x intercepts so in others words if its x-2 then the intercept is 2. then you find the midpoint of the two x intercepts to find the x coordinate of the vertex and then you plug the answer of the midpoint back into orginal equation in first sentence above to find y value
I dislike mathmaticians that introduce useless concepts so we highschoollers have to suffer learning these "algebra" that will have no effect in anyones life. :/
algebra is used in most forms of maths, even the division symbol involves algebra where the dots represent the numerator and denominator of a fraction. its also a bit much to say that algebra will have NO effect in ANYONEs life, it's easy to say that it's already affected my career choice. "we highschoollers" have two main subjects that will get us the furthest with careers: English for communication in general, and maths for most careers. For example my mum is currently studying psychology in Uni and a large part of it is graphing. you're allowed to dislike it but speak for yourself
