Question

Select the graph of the solution. |x| =1

Closed circles on -1 and 1 with no line
Open circles on -1 and 1 with arrows pointing away
Open circles on 0.5 with a line connecting -0.5
And |x| = 2
Solid line with closed circles
No line with closed circles
No line with open circles
Thank you. Can u pleAse describe the graph?

Answer 1

Why not actually graph |x|=1? You will find that x = 1 and x = -1 are solutions.
Thus, "closed circles on -1 and 1 with no line" is correct.
