16.
Give the algebraic definition of the derivative of y = f(x) at the point
(a, f(a)). You must use a complete sentences to get any credit at all.
17. Find the slope of the line tangent to
f(x) = 4x2 - 3x - 1 at x = 1.
18.
Draw the f(x) vs x and fÕÕ(x) vs x (assume the object starts at the origin
) graphs for the given fÕ(x) vs x graph.
Differentiate the function: (means find f ' (x) ).
19.
f(x) = x + 1
20.
f(x) = 4 x2 - 3 x - 6
21.
f(x) = sin x
22.
23.
f(x) = x2 sin (x)
24.
f(x) = cos (5x2)
