Ira Lisetskai [31]

Answer:

\huge\boxed{f^{-1}(x)=\dfrac{1}{5}x-3}

Step-by-step explanation:

f(x)=5x+15\to y=5x+15\\\\\text{exchange x to y and vice versa}\\\\x=5y+15\\\\\text{solve for}\ y\\\\5y+15=x\qquad|\text{subtract 15 from both sides}\\\\5y=x-15\qquad|\text{divide both sides by 5}\\\\y=\dfrac{1}{5}x-3
