Question

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

x=−2
and x=2


x=−4
and x=4


x=−16
and x=16


There are no x-intercepts.

Answer 1

x = −2 and x = 2

Reason: The translated function is g(x) = x^2 − 4. Set 0 = x^2 − 4 → x^2 = 4 → x = ±2 (points (−2,0) and (2,0)).
