Let's find the intervals for which the polynomial f (x)= (x+3) (x-1)^2 f (x) = (x +3)(x −1)2 is positive and the intervals for which it is negative. The zeros of f f are -3 −3 and 1 1. This creates three intervals over which the sign of f f is constant: Let’s find the sign of ...

Using Interval Notation. Indicating the solution to an inequality such as x ≥ 4 x ≥ 4 can be achieved in several ways. We can use a number line as shown in Figure 2. The blue ray begins at x = 4 x = 4 and, as indicated by the arrowhead, continues to infinity, which illustrates that the solution set includes all real numbers greater than ...
