Exercise 19 Page 314

Solution Set: {c|c is a real number.}
Graph:

Practice makes perfect
All absolute value expressions are greater than or equal to zero. It follows then that any absolute value expression is greater than all negative numbers.

|- 2c-3|≥ 0 ⇒ |- 2c-3|>- 4 This means any value of c will satisfy the inequality. Therefore, there are infinitely many solutions, and the solution set is the set of all real numbers. We can represent this graphically on a number line by showing that all values are included in the solution set, so all values are shaded.
