How do you slove this problem.. f(4)f(x)= 4-2x^2
I need help with a function in Algebra which is posted below
I think you have the function f(x)= 4 - 2x2 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*22 = ?
Is this all of the information? What is the function f(x) for this relationship? Or, are there more directions for it?
