Question

Which function below is the inverse of f(x)= 7x-1/2

Answer 1

Answer: $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$

Step-by-step explanation:

If we have y=7x-1/2, the inverse is where we solve for x instead of y.

We can isolate x to get 7x=y+1/2, then divide by 7 to get x=y/7+1/14.

Therefore, $f^{-1}(x)=\frac{x}{7}+\frac{1}{14}$.
