Answer: f-1(x) = x/3 + 5/3
Step-by-step explanation: The inverse function is found by replacing the independent variable with the dependent variable and vice versa like so
f(x) = 3x-5 becomes x = 3y-5; now we solve for y
3y = x +5 or y = x/3 + 5/3
Therefore the inverse function becomes: f-1(x) = x/3 + 5/3
