Discussion:
Q: In recession, congress decided to stimulate the economy by providing funds to hire unemployed workers for gov. projects. Suppose the t months after the stimulus programs have begun, there are N(t) thousand people unemployed, where:
N(t)= -t^3 + 45t^2+408t + 3078
a) What is the max # of unemployed workers? When does the minimum level of unemployment happen?
b)In order to avoid over-stimulating the economy, a decision was made to terminate the program as soon as the rate of unemployment begins to decline. When does this occur? At this time, how many people are unemployed?
