What is the inverse function of d(x ) = -2x - 6?

The inverse function is f(x) =

You can find the inverse of any function by switching the d(x) value and the x value. Then solve for the new d(x) value. The result will be your inverse function. Below is the step-by-step process for solving this one.

d(x) = -2x - 6 ---> Switch the f(x) and x values

x = -2f(x) - 6 ---> Add 6 to both sides

x + 6 = 2f(x) ----> Divide each side by -2.

= f(x) ---> Switch the order so that it looks like a function.

f(x) =

And that would be your inverse function.
