Answer:

AB = $\sqrt{20}$

Step-by-step explanation:

calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = B (3, 2 ) and (x₂, y₂ ) = A (7, 4 )

AB = $\sqrt{(7-3)^2+(4-2)^2}$

= $\sqrt{4^2+2^2}$

= $\sqrt{16+4}$

= $\sqrt{20}$

≈ 4.47 ( to 2 dec. places )

Find the limit, if it exists. (If an answer does not exist, enter DNE.)

Charra [1.4K]

Note that your function can be written as

$\begin{cases}\frac{2-(-x)}{2+x}&\text{if } x0\end{cases} = \begin{cases}\frac{2+x}{2+x}&\text{if } x0\end{cases} = \begin{cases}1&\text{if } x0\end{cases}$

So, if x is negative, your function is identically equal to 1. In particular, the limit as x approaches -2 will be 1 as well.
