👉 Learn about the parts of a parabola. A parabola is the shape of the graph of a quadratic equation. A regular palabola is the parabola that is facing either up or down while an irregular parabola faces left or right. A quadratic equation is an equation whose highest exponent in the variable(s) is 2.
The parts of a parabola include: the axis of symmetry (the line passing through the vertex of the parabola to which the parabola is symmetric about), the vertex (the point at which the parabola turns), the domain (the set of possible x-values of the parabola, usually all real numbers for regular parabolas), the range (the possible y-values of the parabola which is usually the region above the vertex inclusive or below the vertex inclusive for regular parabolas), the x-intercepts (the points where the parabola cuts the x-axis) and the y-intercepts (the point(s) where the parabola cuts the y axis.

At 4:13 he messed up the first X-intercept. He wrote (-4,0), when it would be symetrical if it were (-3,0). Because the vertex is not on the Y-axis.

4*1=4 the last term, and 4+1=5 the middle coefficient. Multiply out the binomials and you will see the original problem

@jameswindolf5939 7 лет назад

This is great and all, but I came here to try to find examples of ugly problems that don't have pretty easy squares. It seems that my book and all these videos on RU-vid are the same. The easy, best case scenario of a problem is explained. Then I have to figure out the garbage bullshit ones in my book on my own somehow. FUCK!!!

@brianmclogan 7 лет назад

What type of problem are you looking for, rational? quadratic? I have multiple different examples

@jameswindolf5939 7 лет назад

Wow. Look at you responding almost immediately! Thanks, man! So the problems I am seeing are ones with negative "a" and ones that don't pack into a neat little square. I'm left with fractions and radicals that I can't seem to work into a square.

@brianmclogan 7 лет назад

yea, most of my videos are not labeled to determining the x and y intercepts but I the best option would be solving using quadratic formula, or solve by completing the square. When solving you are technically determining the x-intercepts. Y-intercepts you just plug in zero for x and solve for y

To be fair it was pretty easy. But the thing is there is factoring problems that are so hard to factor because they include really big numbers. There’s probably a video out for it, I’ll check.

Mr. Logan...I really need your help. If my quadratic equation is x^2-4x+5....how can I figure out the x intercepts? Positive 5 does not have two numbers to make it positive five and also equal -4. If I take the entire equation and multiply it by -1, then -x^2 will still not come out correctly.
