Answer:sd

D.
f\left(x\right)=2x^2+3x-5

Explanation:

Given choices are:


f\left(x\right)=(2)/(x^2)


f\left(x\right)=3\left(3-x\right)


f\left(x\right)=7^2


f\left(x\right)=2x^2+3x-5

Now we need to find about which of them is the quadratic function.

We know that quadratic function is written in form of
f\left(x\right)=ax^2+bx+c

Last choice looks similar to that form.

Hence coorect choice is D.
f\left(x\right)=2x^2+3x-5
