Question

which is the parent quadratic function?A. F(x)=x^2B. F(x)=xC. F(x)=x^4D. F(x)=-x

Answer 1

First, the functions of the options B. and D. are not quadratic functions because their degree is 1.

On the other hand, the simplest parabola,

$y=x^2$

Is known as the Parent Quadratic Function, because all other parabolas, or quadratic functions, can be obtained from this graph by one or more transformations.

Therefore, the correct answer is

$A\text{. }F(x)=x^2$
