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

x = 8

Step-by-step explanation:

To find the x- intercept equate f(x) to zero, that is

x² - 16x + 64 = 0 ← factor the quadratic

(x - 8)(x - 8) = (x - 8)² = 0

Equate each factor to zero and solve for x

x - 8 = 0 ⇒ x = 8

x - 8 = 0 ⇒ x = 8

the x- intercept is x = 8 with multiplicity 2, indicating that the graph has a turning point on the x- axis at this point.

The x- intercept is (8, 0 )

X= 8 so the correct answer is (8,0)

Step-by-step explanation:

x-intercept y = 0

(x-8)(x-8) = 0

so x - 8 = 0 so x =8

Hope this helps! :)

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
