Find the x-intercepts of the function.
-$f ( x ) = x ^ { 2 } - 64$
A)x-intercept: (8, 0)
B) $x \text {-intercept: } ( 2 \sqrt { 2 } , 0 ) , x \text {-intercept: } ( - 2 \sqrt { 2 } , 0 )$
C)x-intercept: (8, 0), x-intercept: (-8, 0)
D)x-intercept: (-8, 0)

Question

Quizplus · Accepted Answer

The x-intercepts occur where the function equals zero: $x^2 - 64 = 0$. Solving gives $x^2 = 64$, so $x = 8$ or $x = -8$. Thus, the x-intercepts are (8, 0) and (-8, 0).
