Question

for WorldBoy:
f(x)=-7/2x -3
g(x)=-2x+6/7

Answer 1

ok, you understand the problem?

Answer 2

WB, I'll assume the x is not in the denominator

Answer 3

like amistre64 said, to do compositions, put f(x) or g(x) in for x

Answer 4

no

Answer 5

in this one, you cross multi

Answer 6

f(x)=-7/2x -3
g(x)=-2x+6/7

f(g(x)) = -7/2g(x) -3
f(g(x)) = -7/2(-2x+6/7 ) -3

It's all about parentheses

Answer 7

oh my, god this was the simples thing ever,

Answer 8

thx, i won't need more help tonks.

Answer 9

f(g(x)) = -7/2(-2x+6/7 ) -3
= 7x - 3 -3 when you distribute
= 7x -6 when you combine like terms

Answer 10

okay

Answer 11
