1. which one of the following does not find the value of f '(3) for f(x) = 3x2 - 4x + 1? (4 points)

a f prime of 3 equals the limit as h approaches 0 of the quotient of the quantity 3 times the square of the quantity 3 plus h minus 4 times the quantity 3 plus h plus 1 minus the quantity 3 times 3 squared minus 4 times 3 plus 1, and h

b f prime of 3 equals the limit as h approaches 0 of the quotient of the quantity 3 times the square of the quantity 3 plus h minus 4 times the quantity 3 plus h plus 1 minus 3 times 3 squared plus 4 times 3 minus 1, and h

c f prime of 3 equals the limit as x approaches 3 of the quotient of 3 times x squared minus 4 times x plus 1 minus 16, and the quantity x minus 3

d all of these find the value for f '(3).

2. use your graphing calculator to find the value of f '(0) for f(x) = cos(x) - ex

3. find the equation of the line tangent to y = -3x2 + x - 5 at x = -1
