An image of a parabolic lens is projected onto a graph. the y-intercept of the graph is (0, 90), and the zeros are 5 and 9. which equation models the function? y = 90(x – 5)(x – 9) y = 2(x – 5)(x – 9) y = 90(x + 5)(x + 9) y = 2(x + 5)(x + 9)

Using the Factor Theorem, the equation that models the function is:

The Factor Theorem states that a polynomial function with roots is given by:

In this problem, the zeros are 5 and 9, hence , and:

The y-intercept of the graph is (0, 90), which means that when , which is used to find a.

Then, the equation is:

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
