Question

can some one help me solve the equation f(x)=5x+12. find f-1(x)

Answer 1

\(y=5x+12\) one approach is to switch the \(x'a \text{ and } y's\) and then solve for \(y\).

\(y=5x+12 \rightarrow x=5y+12 \rightarrow x-12=5y \rightarrow y = \frac{x-12}{5}\)
so
\[f^{-1}(x)=\frac{x-12}{5}\]

Answer 2

that should say
"one approach is to switch the x's and y's"

Answer 3

thnx
