Examine the graph of functions $f(x)$ and $g(x)$ at right. Use the graph to approximate the values below (if possible).

1. $f\left(0\right)$ 

   Hint (a):

   When $x$ is $0$ in the relation $f\left(x\right)$, what is $y$?

   Answer (a):

   $f\left(0\right) = 3$

2. $g(4)$ 

   Hint (b):

   When $x$ is $4$ in the relation $g\left(x\right)$, what is $y$?

   Answer (b):

   $g\left(4\right) = 2$

3. $f(2)$ 

   Hint (c):

   See the hint for part (a).

4. $g(0)$ 

   Hint (d):

   See the hint for part (b).

5. $g(2)$ 

   Hint (e):

   See the hint for part (b).

6. $f(5)$ 

   Hint (f):

   Is there a $y$-value for $f\left(x\right)$ when $x$ is $5$?
