Question

Help finding the x & y intercept

Answer 1

The x-intercept will be the value of x when y=0.  The solutions to (x+1)(x+2)=0 are -1 and -2 since we can substitute them in to have one of the values in parentheses equal to zero, so our x-intercepts are (-1, 0) and (-2, 0).  The y-intercept is the value of y when x=0, or (0+1)(0+2)=2.  Therefore, the y-intercept is (0, 2).
