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(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.
Given that f(x)= 2x-5 and g(x) =x^2-31, calculate the value of
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?
