The vertex form of all expressions is given below.
We have given that the expressions
We have to write the function in vertex form.
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
[tex]f(x)=(x-1)^2-7[/tex]
it can be written as
[tex]f(x)=1(x-1)^2+(-7)[/tex]
The second equation can be written as
[tex]f(x) = (x+1)^2 -7[/tex]
vertex for is,
[tex]f(x)=1(x-(-1))^2+(-7)[/tex]
The third equation is,
[tex]f(x) = (x -1)^2 - 5[/tex]
Vertex form is,
[tex]f(x)=1(x-1)^2+(-5)[/tex]
Forth equation is,
[tex]f(x) = (x +1)^2 +(- 5)[/tex]
Vertex form is,
[tex]f(x) =1 (x -(-1))^2 +(- 5)[/tex]
