.)

\newline

\begin{array}{c|c} \hline x & f(x) \ \hline -2 & -1 \ -1 & -2 \ 0 & 1 \ 1 & 4 \ 2 & 7 \ 3 & 10 \ \hline \end{array}

Determine $x$ for $f(-2)$ : To find $f^{-1}(-2)$ , we need to determine the value of $x$ for which $f(x) = -2$ . We can use the given table to find this value.
Find $x$ for $f(-2)$ : Looking at the table, we find the $x$ -value that corresponds to $f(x) = -2$ . We see that when $x = -1$ , $f(x) = -2$ .
Conclusion for $f^{-1}(-2)$ : Since $f^{-1}(-2)$ is asking for the $x$ -value that gives an output of $-2$ for the function $f(x)$ , we can conclude that $f^{-1}(-2) = -1$ .

Consider the following problem:

\newline

The population of ants in Chloe's ant farm changes at a rate of

r(t)=-15.8 \cdot 0.9^{t}

ants per month (where

t

is time in months). At time

t=0

, the ant farm's population is

150

ants. How many ants are in the farm at

t=4

\newline

Which expression can we use to solve the problem?

\newline

\int_{0}^{4} r(t) d t

\newline

\int_{3}^{4} r(t) d t

\newline

150+\int_{3}^{4} r(t) d t
