Math Problem Statement
The polynomial function A(t)equals0.003407t Superscript 3minus0.03764t Superscript 2plus0.1068tplus0.007 gives the approximate blood alcohol concentration in a person t hours after drinking some alcohol on an empty stomach, for t in the interval [0,5]. a. Graph A(t) on 0less than or equalstless than or equals5. b. Using the graph from part a, estimate the time of maximum alcohol concentration. c. Use the graph from part a to estimate the period in which the concentration of the alcohol in the person exceeds 0.05.
