Homework Statement


Sketch a graph of a function that satisfies the stated conditions:
lim f(x) [as x approaches 2) = 3 and f(2) = 4.


Homework Equations


N/A


The Attempt at a Solution


I know that the graph looks like an absolute value function (because the professor told me), but I'm really confused when I draw it out. As x approaches 2, the limit is 3. To me, this meant that the vertex of the graph is the coordinate (2,3) since 3 was the limit. However, when x=2, y=4, and the points can't coexist on this graph. What am I figuring/looking at wrong?

If this is the problem as given, it has nothing to do with an absolute value function.

It's a graph with a "hole" in it.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
