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(x), what is y?

   Answer (a):

   f(0) = 3

2. $g(4)$

   Hint (b):

   When x is 4 in the relation g(x), what is y?

   Answer (b):

   g(4) = 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(x) when x is 5?

7. $x\text{ such that}f(x)=g(x)$

   Hint (g):

   For what x value are the two functions equal?
