Answer:sd

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

Step-by-step explanation:

Given choices are:

[tex]f\left(x\right)=\frac{2}{x^2}[/tex]

[tex]f\left(x\right)=3\left(3-x\right)[/tex]

[tex]f\left(x\right)=7^2[/tex]

[tex]f\left(x\right)=2x^2+3x-5[/tex]

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

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

Last choice looks similar to that form.

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