Question

Evaluate the limit and justify each step by indicating the appropriate limit law(s).

$\underset{t\to 3}{\lim }4t$

Short answer

The value of limit of the given function is$12$.

Step-by-step solution

Step 1. Given information.

The limit of function is given here,

$\underset{t\to 3}{\lim }4t$

Step 2. Formula used.

Here, we use concept of multiple.

Step 3. Simplification.

Given, $\underset{t\to 3}{\lim }4t$

$\begin{array}{c}\underset{t\to 3}{\lim }4t\\ \lim 4t=4\times 3\\ =12\end{array}$

Therefore, our final answer is$12.$
