How do you slove this problem.. f(4)f(x)= 4-2x^2

I think you have the function **f(x)= 4 - 2x**^{2 }and you want to evaluate it for when** x = 4**. If so, you're finding
**f(4)**, so you'd plug in 4 as x, like so:

f(4) = 4 - 2*2^{2} = ?

Tutors, sign in to answer this question.

I think you have the function **f(x)= 4 - 2x**^{2 }and you want to evaluate it for when** x = 4**. If so, you're finding
**f(4)**, so you'd plug in 4 as x, like so:

f(4) = 4 - 2*2^{2} = ?

Is this all of the information? What is the function f(x) for this relationship? Or, are there more directions for it?
