The image shows a geometric representation of the function f(x) = x2 – 2x – 6 written in standard form.

what is this function written in vertex form?

f(x) = (x –1)2 – 7

f(x) = (x +1)2 – 7

f(x) = (x –1)2 – 5

f(x) = (x +1)2 – 5

we know that

To find the equation in vertex form, we need to factor the function

so

Complete the square. Remember to balance the equation

Rewrite as perfect squares

in this problem

the vertex is the point

therefore

the answer is

The function written in vertex form is equal to

answer: .75 km
