  y=2x+3 How do you find the inverse of this function? I know that you have to get the x by itself but i am not sure how.

  • Math -

    I do it this way:
    1. switch the x and y variables to get
    x = 2y + 3
    2. solve this new equation for y
    2y = x - 3
    y = (1/2)x - 3/2

    some people solve the original for x fist, then switch the variables.

    -makes no difference, same number of steps, same work, same result.
