5. Inequalities Involving Absolute Value
Sign In
Create an or
compound inequality because the absolute value is greater than the given value.
Solution Set: {k | k<1 or k>7}
Graph:
Let's isolate k in both of these cases before graphing the solution set.
The solution to this type of compound inequality is the combination of the solution sets. First Solution Set:& k>7 Second Solution Set:& k< 1 Combined Solution Set:& k< 1 or k>7
The graph of this inequality includes all values less than 1 or greater than 7. We show this by keeping the endpoints open.
