I don't know if I am right or not

Given is a graph of a portion of the postage function, which depicts the cost (in cents) of mailing a letter, p, versus the weight (in ounces) of the letter, x. Find each limit, if it exists:

lim p(x), lim p(x), lim p(x)

x -->3^ - x --> 3^+ x --> 3




I was able to find that it is 77, 99 and the last one does not exist, but I don't know if this is the correct order

I'm unfamiliar with your notation. Guessing x -->3^ -
means x->3 from the left
x --> 3^+
means x->3 from the right
x --> 3
means x->3 from both
I agree with your answers and the order.
