Question 995428: Use your graphing calculator to find the values of x for which x^2 - 3x - 18 < 0. Are these the same values of x you found in x^2 - 12 , 3x + 6?
I know that they should be the same values, but how do you tell what the values of x are from graphing it?

x%5E2-3x-18%3C0
%28x%2B3%29%28x-6%29%3C0
critical values are x at -3 and +6.
Parabola opening upward with vertex as a minimum.
Solution for the inequality -3%3Cx%3C6. Check each of the three intervals on the number line to see which intervals satisfy and which do not satisfy the inequality.
