1. Use the definition of the derivative to find f(x) given f(x) = square root (x).

2. A ball thrown vertically upward at time t = 0 (s) with initial velocity 80 ft/s and with initial height 96 ft has height function:

y(t) = -16t^2 + 80t + 96.

a) What is the maximum height attained by the ball?

b) When and with what impact speed does the ball hit the ground?

3. Write an equation of the line tangent to the curve y = (5/x^2) - (2/x^3) at the point P(-1, 7). Express the answer in the form ax + by = c.

4. Given f(x) = ((x^2 + 3x + 1)^5) / ((x + 3)^5), identify a function u of x and an integer n =/= 1 such that f(x) = u^n. Then compute f'(x).

5. Differentiate the function f(x) = (1 + x)^(3/2)(2 + x)^(2/3).
