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

where did u get the 4 from?

The four came from (x^{2})
two squared is 4 
Wow, I'm so confused. Can somebody just solve this problem step by step please?

This is pretty basic. I suggest a tutor.
