Using graphing technology, approximate the solutions of 0.91x2 − 0.54x − 4.9 = 0. x ≈ −2.32 and x ≈ 2.56 x ≈ −2.14 and x ≈ 2.44 x ≈ −2.18 and x ≈ 2.53 x ≈ −2.04 and x ≈ 2.64
What kind of graphing calculator do you have? I use a TI-83
An expandable PDF plot from Mathematica 8 Home Edition is attached.
