Where are the answers to all these questions? How would i know that i have done correctly?

@GallingEssay 2 месяца назад

The answer to the qst question is very time consuming. Instead, we can just say that vertex is the lowest point in a parabola and all other points will have greater value of f(x). Therefore, the answer is -12. Also, it may help in some other question, but you can say a+b+c=f(1)

@manashkoirala5029 Месяц назад

Ohh

@haziquniverse 17 дней назад

Thanks you, but I don’t get it, how does it help us assume that it is good to say a+b+c=f(1) to answer the question?

@GallingEssay 17 дней назад

@@haziquniverse It doesn't help in this question, But in other questions, it may help

@OverclockingCowboy 13 дней назад

@@haziquniverse The vertex is at f(9). If f(1) > f(9), the parabola opens upward. Hence, a+b+c > -12.

@haziquniverse 13 дней назад

⁠@@OverclockingCowboy So what you are trying to say is that, since the vertex is the lowest point any value of x will lead to a larger value of f(x) than f(9); So, we can say f(1) will be greater than f(9); we know what both of them are: This helps us say a+b+c > -14

For 3rd one If you're going to attempt digital sat Jut put the equation in desmos And put the options give "r" any value which ever point lies on the Line for every value of "r" that's your answer Cause these eq are same they have infinitely many solutions So whichever the value of r is the correct solution (point) will always be on the graph

@joaofantini7265 Год назад

Took the DSAT today and the last question was similar to your first question in the video. In the test, the question gave the roots to the function and asked for the sum a + b. For anyone wanting to try out the question the coordenates given were (12,0) and (-6,0) and a > 1. Answer is -10

@user-cp9zs1tr5j 10 месяцев назад

@@user-nj5yq1yb6t Hi, I tried to solve this question too, and here is my work process: When the roots are (12,0) and (-6,0), and a > 1, we know that the factored form of the quadratic function is: y = a(x-12)(x+6) When we expand this into the form [ax^2 +bx +c], it is: y = a(x^2 -6x-72) --> y = ax^2 -6ax -72a Now here, I am assuming that the question asked for the SMALLEST value of (a+b). Then we can assume that the value of 'a' is 2 (since the smallest value that satisfies a>1 is 2). a = a = 2 b = -6a = -6*2 = -12 Finally, the values of a+b would be: 2+(-12) = -10 Therefore, the answer is -10. Sorry if my explanation isn't that great. I hope it made sense!

All these questions have simpler and logic way to figure out the solutions efficiently and accurately. The first step is not to calculate but to analyze. For example, the 2nd question, since you've gotten kj=-45, so j=-45/k; and the question said that j is an integer so -45/k is an integer, then 45/k is also an integer.

@JohnSAT 10 месяцев назад

@abhinavgottipati Год назад

We can estimate where the vertex is, and the question says that there are two solutions. Therefore, we know that the graph must open upwards in order to meet and intersect the x-axis. After expanding vertex form, we can simplify and find the equation for a. The minimum value of a must be 0.0000000001 ( or higher than 1), there it is impossible to attain any other value for the answer.

@brandon-qw5eu Год назад

first response is correct, but in simpler terms, it's because 14 subtracted from any positive number will equal a number greater than -14. Answer choices A and B are both less than -14, so they can't be correct. Answer choice C is -14, which is also incorrect because -14 is not greater than -14. Therefore D is the only possible answer.

Since the “a” must be positive,we should plug in a option which will cause the value of “a” be positive,means the number should be larger than -14 (=>-12) so that their sum will be positive.-12+14=2,which is positive ✅

The parabola intersects x-axis at 2 points,also it is given that the vertex of that parabola is (9,-14) , so if you draw it on xy-plane it is clear that a should be positive.

The parabola has a vertex positioned under the x-axis so if the it opened upward it would intersect the x-axis ( which it did ) and if opens down then it wouldn't intersect at all - just because the vertex is underneath the x-axis
