If f(x) and f^-1(X) are inverse functions of each other and f(x)=2x+5, what I f^-1(8)

podryga [215]

Answer: 3/5

Step-by-step explanation:

First, you need to find the inverse of f(x)=2x+5 .

$f-1(x)= \frac{x}{2} -\frac{5}{2}$

Then, you'd plug in 8 into that equation, which I got $\frac{3}{5\\}$

Hope this helps :)
