What is the x-intercept of the graph of the function f(x)=x^2-16x+64

The x-intercept is 8

Step-by-step explanation:

The x intercepts of a graph is when the y value is equal to 0. To find this, we put 0 in for f(x)

0 = x^2 - 16x + 64

Next we can factor the equation so that we can solve this.

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

Now that we've done this, we can combine the terms

0 = (x - 8)^2

And using this we can now solve for x.

0 = (x - 8)^2

0 = x - 8

8 = x

(8,0)
