0
The y-intercept is easy to find. Substitute 0 for x. It crosses the y-axis at 20, (0,20).
To find the x- intercepts substitute 0 for y and solve. Since this creates a quadratic equation, it is a little harder.
0 = x2 + 9x + 20, can be solved by several methods, factoring is easiest.
(x+5)(x+4) = 0
x = -5 and x = -4
So it crosses the x-axis at two points, -5 and -4, (-5,0) and (-4,0)
