Question

Find the vertex f(x)=8(x-21)²

Answer 1

(21,0)

Explanation:

The function of the parabola is given in vertex form which is
`f(x) = a(x-h)^(2) +k`

The vertex is equal to (h,k). Looking the function
`f(x)=8(x-21)^(2)`, we see that the h-value is equal to 21 and that the k-value is 0. So the vertex of the function is (21,0).
