Question

use factoring to find the zeros of the function. use the zeros to find the vertex of its graph.
y=x^2-x-132

Answer 1

x^2-x-132 = 0
(x-12)(x+11) = 0
If the product of two factors is 0, then either factor may be zero.
x - 12 = 0 and x + 11 = 0
x = 12 and x = -11

Answer 2

and vertex is half way between the zeros
