All this is asking you to do is plug in -2 for x

So

f(x)=3x²-4

f(-2)=3(-2²)-4

f(-2)=12-4

f(-2)=8

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Unless there is none then in that case there very well may be infinite solutions
