2. Thm 2.2 The Constant Rule The derivative of a constant function is 0. That is, if c is a real number, then Examples: FunctionDerivative a.y = 7dy/dx = b.f(x) = 0f’(x) = c.s(t) = -3s’(t) = d.y = kπ 2, k is constanty’ =

3. Thm 2.3 The Power Rule If n is a rational number, then the function f(x) = x n is differentiable and d/dx[x n ]=nx n-1 For f to be differentiable at x=0, n must be a number such that x n-1 is defined on an interval containing 0.

5. Find the slope of the graph of f(x) = x 4 when a. x = -1 b. x = 0 c. x = 1

6. Find an equation of the tangent line to the graph of f(x) = x 2 when x = -2

7. Thm 2.4 The Constant Multiple Rule If f is a differentiable function and c is a real number, then cf is also differentiable and d/dx [cf(x)] = cf’(x) Thm 2.5 The Sum and Difference Rules The sum (or difference) of two differentiable functions f and g is itself differentiable. Moreover, the derivative of f+g (or f-g) is the sum (or difference) of the derivatives of f and g.

14. The position function for a projectile is s(t) = –16t 2 + v 0 t + h 0, where v 0 represents the initial velocity of the object and h 0 represents the initial height of the object.

15. An object is dropped from the second-highest floor of the Sears Tower, 1542 feet off of the ground. (The top floor was unavailable, occupied by crews taping for the new ABC special "Behind the Final Behind the Rose Final Special, the Most Dramatic Behind the Special Behind the Rose Ever.")  (a) Construct the position and velocity equations for the object in terms of t, where t represents the number of seconds that have elapsed since the object was released.  (b) Calculate the average velocity of the object over the interval t = 2 and t = 3 seconds.  (c) Compute the velocity of the object 1, 2, and 3 seconds after it is released.  (d) How many seconds does it take the object to hit the ground? Report your answer accurate to the thousandths place.  (e) If the object were to hit a six-foot-tall man squarely on the top of the head as he (unluckily) passed beneath, how fast would the object be moving at the moment of impact? Report your answer accurate to the thousandths place.
