Answer 1

Let

Answer 2

ok
do you know how to read it?

Answer 3

Calculate the following limits. Enter DNE for a limit which does not exist.
lim_{x\to -4^-}f(x)=

lim_{x\to -4^+}f(x)

lim_{x\to -4}f(x)

Answer 4

I suppose I do, just dunno how to proceed.

Answer 5

i can't read it, but i can make a guess

Answer 6

\[\lim_{x\to -4^-}f(x)= \]

Answer 7

use the top rule, since \(\lim_{x\to -4^-}\) means \(x<-4\)

Answer 8

in other words, in
\[\sqrt{-3-x}+2\] replace \(x\) by \(-4\) and see what you get
you got this?

Answer 9

\[\lim_{x\to -4^+}f(x) \] use the bottom one, since \(x>-4\)

Answer 10

i.e. replace \(x\) by \(-4\) in the expression \(2x+11\)
