f(x) = 3x – 7 and g(x) = –2x – 6. Find (ƒ ∘ g)(4)
(fo g)(4)
f(g(4))
G(x)=2x6g(4)=2*(4)6g(4)=86
g(4)=14
f(g(4))=f(14)
f(x)=3x7
f(14)=3*(14)7
f(14)=427
f(14)=49
(f o g)(4)=49

What is the inverse of the given relation?
y = 3x + 12
=3x=y12
=x=y/34
=y=x/34
@mathteacher1729 correct?

f(x) = –2x + 4 and g(x) = –6x – 7
f(x) – g(x)
(2x+4) – (6x –7)
2x+4+6x +7
4x+11

f(x) = –2x + 4 and g(x) = –6x – 7
it might be 8x+11 and not 4x+11 >.>
