1. $f(1)$ can be expressed in words as "the value of $f$ when $x$ is 1." Find or compute:

a. The value of $f$ when $x$ is 1.

10

b. Find the value of $f(3)$.

2

c. Find the value of $f(10)$.

37

2. Can you find an $x$-value that would make $f(x)$:

a. Less than 1?

No, from the graph, it seems that 1 is the least value of $f$, and that occurs when $x=4$. All other $x$-values produce outputs that are greater than 1.

b. Greater than 10,000?

Yes, there are lots of $x$-values that produce an output greater than 10,000. For example, both -100 and 110 would make $f(x)$ greater than 10,000.

3. $g(9)$ can be expressed in words as "the value of $g$ when $x$ is 9." Find or compute:

a. Find the value of $g$ when $x$ is 9

-2

b. Find the value of $g(13)$.

6

c. Find the value of $g(2)$.

-93

4. Can you find an $x$-value that would make $g(x)$:

a. Greater than 7?

No, it seems that 7 is the greatest value of $g$, and that occurs when $x=12$. All other $x$-values produce outputs that are less than 7.

b. Less than -10,000?

Yes, there are lots of $x$-values that produce an output less than -10,000. For example, both -200 and 200 would make $g(x)$ greater than -10,000.
