Question

A quadratic function has an equation of f(x) = a(x + 3)2 – 4 and goes through

the point (-2, 2). What is the a-value of the equation?

Answer 1

6

Explanation:

Put the given point into the equation and solve for a.

f(-2) = a(-2 +3)² -4 = a -4 = 2

a = 6 . . . . . add 4

The a-value in the equation is 6.
