Question

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

Answer 1

The vertex form of all expressions is given below.

We have given that the expressions

We have to write the function in vertex form.

What is the vertex form of the equation?

The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore the first equation

$f(x)=(x-1)^2-7$

it can be written as

$f(x)=1(x-1)^2+(-7)$

The second equation can be written as

$f(x) = (x+1)^2 -7$

vertex for is,

$f(x)=1(x-(-1))^2+(-7)$

The third equation is,

$f(x) = (x -1)^2 - 5$

Vertex form is,

$f(x)=1(x-1)^2+(-5)$

Forth equation is,

$f(x) = (x +1)^2 +(- 5)$

Vertex form is,

$f(x) =1 (x -(-1))^2 +(- 5)$
