Question

I uploaded a picture of the practice problem. I don't know how to do it.

Answer 1

Explanation

We are given the following:

We are required to determine the following:

`\begin{gathered} (a)\text{ }\lim_(x\to-4^-)f(x) \\ (b)\text{ }\lim_(x\to-2^)f(x) \\ (c)\text{ }f(-2) \\ (d)\text{ }\lim_(x\to-1^+)f(x) \end{gathered}`

This can be achieved thus:

(a)

`\lim_(x\to-4^-)f(x)=-1`

(b)

`\lim_(x\to-2)f(x)=-3\text{ \textbraceleft either from the left or right\textbraceright}`

(c)
