Question

How do you graph and find the discontinuities of `y = 3/x`?

Answer 1

The graph would appear like in the figure given

Explanation:

There is discontinuity at x=0, which is quite obvious.

Also as x`->+oo or -oo, y->0`. Similarly, as y`->oo or -oo, x->0` .

The curves pass through (3,1) and (-3,-1). The graph would appear to be like this
