    to find the inverse exchange the x and y and then solve for y

    y = 2x^2

    x = 2y^2

    divide by 2

    x/2 = y^2

    take the square root of each side

    sqrt (x/2) = y

    the inverse of y = 2x^2 is sqrt (x/2)

    y=√2x2,-√2x2y=2x2,-2x2

    Solve for yy and replace with f-1 (x) f-1 (x).
