Question

Find the inverse of:
g(x) = 8x - 3

Answer 1

\( \color{Black}{\Rightarrow y = 8x - 3 }\)

\( \color{Black}{\Rightarrow y + 3 = 8x }\)

\( \color{Black}{\Rightarrow \Large {y + 3 \over 8} = x }\)

Finally just replace y with x and x with g^-1(x)

\( \color{Black}{\Rightarrow g^{-1}(x) = \Large {x + 3 \over 8} }\)
