How do you solve and graph #abs(2c-1)<=7#?
1 Answer
Explanation:
Consider a general inequality with the absolute value:
By definition this is equivalent to solving the following inequalities:
In our specific case this means:
So let's solve the first one:
Now the second:
This is the graph of the first inequality:
graph{x <= 4 [-6.244, 6.243, -3.12, 3.123]}
And this of the second:
graph{x => - 3 [-4.163, 1.997, -1.455, 1.624]}
So the solution and the final graph are the common part of the two inequalities:
