Chapter 11 - Section 11.1 - Finding Limits Using Tables and Graphs - Exercise Set: 21

Answer

(a) $\lim_\limits{x\to 2}f(x)=2$ (b) $f(2)=1$

Work Step by Step

Recall that: 1. The limit as $x\to a$ on a graph is the $y$ value that the graph approaches as $x$ approaches $a$. 2. $f(a)$ is the $y$ values of the graph at $x=a$. Using these rules, we observe the graph and find that: (a) $\lim_\limits{x\to 2}f(x)=2$ (b) $f(2)=1$
