To solve an equation by finding x-intercepts, Cynthia graphed the function y=x^3-5x+|2x-3|. Give several possibilities for the original equation.

Thanks

    first of all change to
    |2x-3| = y - x^3 + 5x

    then
    a) 2x - 3 = y - x^3 + 5x or
    b) -2x + 3 = y - x^3 + 5x

    solve each one for y
