Given that f(x)= 2x5 and g(x) =x^231, calculate the value of
1)f(2)= 2(2)5 = 1 is this correct?
2) gf(1)= 131 = 30 is this correct?
3)f indirect 1(3) how do i do this one?

Math 
Reiny,
1) f(2) = 2(2)  5
= 4  5
= 9
2) you found g(1)
if by gf(1) you mean g(f(1))
then
g(f(1)) = g(25))
= g(3)
= (3)^2  31
= 9  31
= 22
3) I don't a clue what you mean by
"f indirect 1(3)"
I have never seen that notation.
