What is the x-intercept of the graph of the function f(x) = x2 − 16x + 64?

(−8, 0)
(0, 8)
(8, 0)
(0, −8)

The x-intercept is when y=0
or in this case f(x) = 0

so

now we factor to find what x equals
we want a pair of numbers that multiply to 64 and add up to -16
this would be -8 and -8

so we can get


if
then

in the format of
if we have and

then our answer would be
