Q. Find

\lim _{x \rightarrow-3} \frac{x+3}{4-\sqrt{2 x+22}}

answer:

\newline

(A)

-3

\newline

(B)

-4

\newline

(C)

-\frac{3}{4}

\newline

(D) The limit doesn't exist

Substitute $x = -3$ : First, let's try to directly substitute $x = -3$ into the expression to see if the limit can be evaluated this way. $\newline$ $\lim_{x \to -3}\frac{x+3}{4-\sqrt{2x+22}}$ $\newline$ $= \frac{-3+3}{4-\sqrt{2(-3)+22}}$ $\newline$ $= \frac{0}{4-\sqrt{-6+22}}$ $\newline$ $= \frac{0}{4-\sqrt{16}}$ $\newline$ $= \frac{0}{4}$ $\newline$ $= 0$
