2. For a minimum wage job, the total pay ($) received for x hours worked is given by P(x) = 15.74x, for A. 0 ≤ x ≤ 80 hours worked in a 2-week pay period. Identify the slope of this linear function, P(x) = = 15.74x, and include units with the slope value. Hint: Units of slope = = rise run = y-units x-units B. Use derivative shortcuts to find an equation for P'(x) and explain what this means about the minimum wage job (including units).

The following graph shows the approximate value of the United States Consumer Price Index (CPI) from December 2006 through July 2007. On the graph titled "CPI Dec 2006-July 2007," the horizontal axis is labeled t and the vertical axis is labeled I(t). The curve begins at the point (0, 202), goes up and right becoming more steep, passes through the approximate point (3.5, 205.5), goes up and right becoming less steep, and ends at the approximate point (7, 208.7). The approximating curve shown on the figure is given by I(t) = −0.04t3 + 0.4t2 + 0.1t + 202 (0 ≤ t ≤ 7), where t is time in months since the start of December 2006.
