    Solve the following equation graphically to two decimal places using a graphing cal..

    1.2 x^2 - 1.3 x - 5.5

    Which values of x, to two decimal places, satisfy the inequality? The answer is -1.67<x<2.75 How do I solve this?

    Could I use a graphing calculator so I can solve for these? I must have two answers.
