Question

use interval notation to find an expression for the solution set of the following inequality:
x(x-1)(x+2) > 0
a. (-2,0)
b. (0,infinity)
c. (-2,0) U (1,infinity)
d. (- infinity,-2) U (0,1)
e. (1,infinity)​

Answer 1

Answer:

You can use interval notation to express where a set of solutions begins and where it ends. Interval notation is a common way to express the solution set to an inequality, and it’s important because it’s how you express solution sets in calculus. Most pre-calculus books and some pre-calculus teachers now require all sets to be written in interval notation
