@iGreen can you help me?

Answer 6

@iGreen.

Answer 7

if you want to find the inverse that means you want to make x the subject

so y=7x-3
y+3=7x

(y+3)/7=x

replace x to be \[f ^{-1}(x)\]
and replace y with x to get

\[f^{-1}(x)=\frac{ x+3 }{ 7 }\]

Answer 8

Inverse in what sense? It may be additive inverse or multiplicative inverse or function inverse. For example, the additive inverse of 2 is -2 and the multiplicative inverse of 2 is 1/2 and for functions, its different

Answer 9

inverse f(x) =(x+3)/7
