Question

sketch the limit as x approaches -3 from the left of h(x)=infinity

Answer 1

How do you sketch h(x)=infinity?

Answer 2

the values get close to 0 but never touch.
i forgot to post the second half of the question. the entire question is:
sketch a function that meets to following criteria:
lim as x approaches -3 from the left of h(x)=infinity and lim as x approaches -3 from the right of h(x)=0. is this even possible?
