Question
Sketch the graph of the function and use it to determine the values of $a$ for which $\lim _{s-o} f(x)$ exists.$$f(x)=\left\{\begin{array}{ll}1+x & \text { if } x<-1 \\x^{2} & \text { if }-1 \leq x<1 \\2-x & \text { if } x \geq 1\end{array}\right.$$
Step 1
The function is defined in three parts: $1+x$ for $x<-1$, $x^{2}$ for $-1 \leq x<1$, and $2-x$ for $x \geq 1$. Show more…

The Limit of a Function
Sketch the graph of the function and use it to determine the values of $a$ for which $\lim _{x \rightarrow a} f(x)$ exists. $$ f(x)=\left\{\begin{array}{ll} \sqrt[3]{x} & \text { if } x \leqslant-1 \\ x & \text { if }-1<x \leqslant 2 \\ (x-1)^{2} & \text { if } x>2 \end{array}\right. $$
