How is this problem done?
IF f(x)=2x^28x3 FIND f(2)

Put in for x the value 2, and compute f(2)

so is the answer f=21/2? if that is right, thank you bobpursley

The answer has to be an integer. In this case, it is 2*4  8*(2)  3 = 21

bobpursley,
The four came from (x^{2})
two squared is 4

bobpursley,
This is pretty basic. I suggest a tutor.
