What is f(x) = x2 – 8x 11 written in vertex form? f(x) = (x – 4)2 – 5 f(x) = (x – 4)2 5 f(x) = (x 4)2 – 27 f(x) = (x 4)2 27?

f(x) = (x - 4)² - 5 is the vertex form

Step-by-step explanation:

Given function is

we have to write this function in the vertex form

Vertex form of a parabola is written in the form of f(x) = a(x - h)²+ k

Now we can convert the original function in the vertex form

f(x) = x²- 8x + 11

f(x) = (x²- 8x + 16) - 5

f(x) = (x - 4)² - 5 [(a - b)² = a² + b²- 2ab]

f(x) = (x -4)² - 5 is the answer.

x=4
