Today in class we went over inequalities, one of which was x^2+3x-10/x^2-6x+9 < 0. When graphed, the equation goes below zero on the x-axis at (-5,0) and above again at (2,0) and has a vertical asymptote at (3,0). Therefore, the values for x when the function is less than zero can be expressed as -5 < x < 2.
HW: POW due Wednesday, October 8, and pg. 388 #1-14
