How do you graph and solve #|2x+3|<=15#?
See a solution process below:
The absolute value function takes any term and transforms it to its non-negative form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.
Now, divide each segment of the system by
Or. in interval notation
To graph this we will draw vertical lines at
The lines will be a solid line because the inequality operators contain "or equal to" clauses.
We will shade between the lines to show the interval:
