(-1,10]
To write: the solution
Answer to Problem 13P
The inequality is
Explanation of Solution
Given:
The solution of inequality is
Calculation:
Steps to write an inequality:
Step1
Consider a variable as x .
Step2
Extreme left point is -1 which is in open bracket. Thus,
Step3
Extreme right point is 10 which are in closed bracket. Hence,
Thus, the inequality is
Thus, the graph of
