Meaning of interval notation
WebTo express a set of real numbers in interval notation, sketch the graph first, using the symbols ( ) or [ ]. Then use these symbols at the endpoints to define the interval. Expressing Sets by Using Interval Notation. Graph the sets on the number line, and express the set in interval notation. a. {x 0 x 3} b. {x 0 x 3} c. {x 0 x. Solution: a. WebSolution We can see that the interval includes values between -6 and 3, but does not include 3. Therefore, the correct interval notation is [-6,3) Intervals and Inequalities. Intervals can be written using inequalities as well. Let us recall that math inequalities are the symbols that stand for less than, less than or equal to, greater than, and greater than or equal to.

Step 1: We write the first and last number of the interval, which are the endpoints of the interval. For example, if the interval is from 6 to 20, we write 6, 20. Step 2: We use a round or square bracket on each side of the two numbers. We use:
WebDetermining the positive and negative intervals of polynomials. 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.
