Question # 1: Find the cubic model that best fits the data. Then, find the First Derivative (dy/dx), Slope (m) at x

=

1 using

dy/dx, and Equation of the Tangent Line at x

=

1. You can use a graphing calculator to obtain the cubic equation and other

information.

Question # 2: Solve the problem.

2) A population grows from an initial size of 80,000 people to an amount P(t), given by

P(t)

= 80,000(1 + 0.3t +

t2), where t is measured in years from 1987. How rapidly is the

growth rate of the population increasing t years from 1987?

Question # 3: Evaluate.
