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

x-intercept: (8,0)

Step-by-step explanation:

Given:

For x-intercept, Put y=0 and solve for x.

x-intercept: It is a point where y-coordinate zero.

Equate each factor to 0 and solve for x

x-8 = 0    , x-8 = 0

x=8,8

x-intercept: (8,0)

Hence, The x-intercept is 8.

4th option

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence , that is

4 - (- 2) = 10 - 4 = 16 - 10 = 6

This indicates the sequence is arithmetic with explicit formula

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 2 and d = 6 , then

= - 2 + 6(n - 1) = - 2 + 6n - 6 = 6n - 8
