Please Help!
Solve the following equation graphically to two decimal places using a graphing calculator.

  1.3x^2 - 1.2x - 5.4 < 0

How do I do this with a TI-84 calculator? Thanks!

-1.63 < x < 2.55

I graphed the equation y = 1.3x^2 - 1.2x - 5.4 and found where it is below the x-axis.  I had to find the zeros using the zero function under CALCULATE 2: zero.
