Question 1089591: Find the x-intercepts of the polynomial function. State whether the graph crosses the x-axis, or touches the x-axis and turns around, at each intercept
f(x) = (x + 1)(x - 5)(x - 1)^2
-1, crosses the x-axis;
5, crosses the x-axis;
1, crosses the x-axis
1, crosses the x-axis;
-5, touches the x-axis and turns around;
-1, touches the x-axis and turns around
-1, crosses the x-axis;
5, crosses the x-axis;
1, touches the x-axis and turns around
1, crosses the x-axis;
