How do you graph and solve # |2x-5| >= -1#?
1 Answer
Just find when
They are never equal.
Explanation:
Quick solution
The left part of the equation is an absolute, so it is always positive with a minimum of 0. Therefore, the left part is always:
Graph solution
This is negative when:
And positive when:
Therefore, for you must graph:
These are both lines. Graph is:
graph{|2x-5| [-0.426, 5.049, -1.618, 1.12]}
As we can clearly see, the graph never passes through
For every
