     o a grapefruit
     o a high diver
     o a trapeze artist named the Great Santini
     o a baseball

2. In this section you found the zeros of a function. How do you find zeros, in general?

3. Carefully read Example 1 on page 89 and the paragraph below it.
    Write the factored form of f(x) = x² − x − 6.

4. Look at Example 3 on page 89. In trying to find zeros of the function
by solving an equation using algebra, the solution found was x  = ______.
Why is this solution not a real number?
______________________________________________________________.
Therefore what would we expect when we look at the graph of a function when
we try to solve for zeros and get no real solutions?

     o none
     o once
     o twice
     o three times
  

6. In Example 5, find all the values of t for which h = f(t) = 10. Use any means you wish but
