MAC 2233 Limit Section 1.5 Consider the following function: f(x) is undefined at x = -3 b f(-3) has no answer. We cannot say anything about the y value at x = -3. Let’s take a look at the behavior of the functions (what the graphs are doing) close to x = -3. Let’s allow the x values to get infinitely close to -3 from its right. x -2.9 -2.99 -2.999 -2.9999
