The tool that allows you to work backwards to determine what input value is required for a specific output value is called “inverse function” or “backward function”. In mathematics, an inverse function is a function that undoes the effect of another function. It takes an output value and gives you the corresponding input value.

For example, let’s say you have a function f(x) = 2x + 3. If you want to find out what input value (x) gives you a specific output value (y), you can use the inverse function to work backwards. The inverse function of f(x) = 2x + 3 is found by swapping the x and y variables and solving for y:

x = 2y + 3

Now, you can solve this equation for y to find the inverse function:

x - 3 = 2y
