#### Answer

(a) To sketch the graph first take the t-vaiues in the x-axis and BAC-values in the y-axis.
Then plot the points given in the table and join them by a curve
(b) Observe the graph, the measure of the BAC increases in 45 minutes and then the measure slowly decreases.
This indicates that the effect of alcohol is high at 45 minutes after rapid consumption and later
the effect of alcohol turns low.

#### Work Step by Step

The given table indicates the number of hours and the blood alcohol concentration (BAC).
