Question

Given the function ƒ(x) = x^ 2 - 4x - 5

Identify the zeros using factorization.
Draw a graph of the function. Its vertex is at (2, -9).

Answer 1

think of two numbers whose product (what you get when you multiply) is \(-5\) and that add to \(-4\)

Answer 2

you only have two choices for two integers that give \(-5\) when you multiply them
