Question

Find the limit Picture below

Answer 1

Answer:

$a. 10$

$b. -1$

Step-by-step explanation:

We want to find;

$\lim_{x \to -1} f(x)$

a. $\lim_{x \to -1} 10$.

Since this is a constant function, the limit is still 10.

$\lim_{x \to -1} 10=10$.

The second one is a limit of a linear function

b.  $\lim_{x \to -1} x$.

We plug in the value to get;

b.  $\lim_{x \to -1} x=-1$.

The correct answer is A

Answer 2

Answer: OPTION A.

Step-by-step explanation:

You can rewrite it as following:

a. $\lim_{x\to \ -1} 10$

This means that you must substitute x=10 into the limit.

There is not x, therefore the result is 10:

 $\lim_{x\to \ -1} 10=10$

b.  $\lim_{x\to \-1} x$

This means that you must substitute x=-1 into the limit. Then:

 $\lim_{x\to \ -1}=-1$
