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

1. ## 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.

What inequality?. All I see is a quadratic expression ...

But we still don't know what the problem was! And we are curious.
