Delbert stands at the top of a \( 300 \) -foot cliff and throws his algebra book directly upward with a velocity of \( 20 \) feet per second. The height of his book above the ground \( t \) seconds later is given by the equation where \( h \) is in feet. \( h = - 16 t ^ { 2 } + 20 t + 300 \) 

Graph the height equation on your calculator. Use your graph and a table of values to help you answer the questions. 

a. When does Delbert's book pass him on its way down?

b. Write and solve an equation to answer the question: How long will it take Debert's book to hit the ground at the bottom of the cliff? 

\(f ( x ) = \left \{ \left . \begin{array} { c c } { c } & { x = - 2 } \\ { 9 } & { x = 1 } \\ { \frac { x ^ { 2 } - 4 } { ( x + 2 ) ( x - 3 ) } } & { \text { otherwise } } \end{array} \right . \text { continuous at } x = - 2 ? \right .\)

(A) Differentiate the given equation implicitly and then solve for \(y ^ { \prime } \) . 

(B) Solve the given equation for \(y\) and then differentiate directly. 

\(5 x ^ { 3 } - 8 y - 6 = 0\) 

(A) First, differentiate \(5 x ^ { 3 } - 8 y - 6 = 0\) implicitly, term by term. 

\(\frac { d } { d x } ( 5 x ^ { 3 } ) = \square \)
