Let f(x)=(x−7)(x+6)(x−5). Find the y-intercept(s), the x-intercept(s), the values of x where f(x)>0, and the values of x where f(x)<0. Do not sketch the graph.
1. Find the y-intercept(s). List your answers as points in the form (a,b)
2.Find the x-intercept(s). List your answers as points in the form (a,b)
3. What are the values of x where f(x)>0?
4. What are the values of x where f(x)<0
