What is the inverse function of f(x)=5x-3

The inverse of this function is f(x) = .

You can find the inverse to any function by switching the x and f(x) values. After that, solve for the new f(x) value. The result will be the inverse function. The step-by-step process for this one is done below for you.

f(x) = 5x - 3 ----> Switch the x and f(x) values

x = 5f(x) - 3 ----> Add 3 to both sides

x + 3 = 5f(x) ----> Divide both sides by 5

= f(x) ----> Switch the order for formatting purposes

f(x) =

And that would be your inverse function.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
