Question

Determine the x-intercept(s) of the function that translates the original function f(x)=x2
down 4 units.(1 point)

x=−4
and x=4


There are no x-intercepts.

x=−2
and x=2


x=−16
and x=16

Answer 1

x = −2 and x = 2

Because the translated function is g(x) = x^2 − 4. Set 0 = x^2 − 4 → x^2 = 4 → x = ±2.
