Question

Could someone help me with this question.

Determine what limit would be represented by the following graph.

I am not sure if it has open dot or closed but what would the equation be for open and closed dot?

Answer 1

I don't see any dot. Also, it appears that the line at y=1 extends for all x, and for y=-1 only for x<0

Assuming thet the graph is

y = -1 for x < 0
y = 1 for x > 0,

it could be y = |x|/x

If the line at y=1 extends for all x, then we could have

y^2 = 1 for x<0
y = 1 for x > 0
