MULTIPLE CHOICE QUESTION

1 min • 1 pt

What is the vertex form of the following quadratic equation?

f(x)=(2x+2)−10f\left(x\right)=\left(2x+2\right)-10  

f(x)=(2x+2)2+10f\left(x\right)=\left(2x+2\right)^2+10  

f(x)=2(x+2)2+10f\left(x\right)=2\left(x+2\right)^2+10  

f(x)=2(x+2)2−10f\left(x\right)=2\left(x+2\right)^2-10
