Question

F(×)=15,000+1.5× what is the inverse

Answer 1

we have the following:

`f\mleft(x\mright)=15,000+1.5x`

the inverse is:

`\begin{gathered} y=15000+1.5x \\ x=15000+1.5y \\ 1.5y=x-15000 \\ (3)/(2)y=x-15000 \\ y=(2)/(3)(x-15000) \end{gathered}`

therefore, the answer is:

`f(x)=(2)/(3)(x-15000)`
