Find the inverse function for the function y = 2x.

Consider what the inverse function means by the example of y = 2x.
The inverse function is such an equation that at x, on the left side, the same value came out. In order to use the original and the inverse equation, substituting the same value for the variable (x), one answer came out.
That is, so that for (y) on the left side and that for (x) the same answer comes out.
You just need to move 2 to the left side of the equation.
Answer: x = y / 2.
