1)f(-2)= 2(-2)-5 = -1 is this correct?

2) gf(1)= 1-31 = -30 is this correct?

3)f indirect 1(3) how do i do this one?

**Reiny**, Tuesday, June 16, 2009 at 1:44pm1) 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(2-5))

= 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.
