(6 points) The linear function y=2x+26 models the average cost of a haircut in a certain city, where y, is the average price of a haircut x years after 2000. Find the slope for the model. Then describe what this means in terms of the unit rate of change in the average cost of a haircut over time. a) m= 26 b) The average cost of a haircut in this city increased (Enter: increased or decreased or not changed ) at a rate of 2 per year after 2000.
Homework Answers
a) comparing the model with y= mx + c the slope of the model is m= 2 and y intercept c = 26
b) the slope gives the rate of change it means that the avarage rate of a haircut increasea at the rate of 2 per year after 2000

Consider the following function. f(x) = x2 + 5x − 6 Find the average rate of change of the function over the interval [0, 1]. Change in y/change in x = Compare this rate with the instantaneous rates of change at the endpoints of the interval. f'(0) = f '(1) = Find the marginal cost for producing x units. (The cost is measured in dollars.) C = 455 + 6.75x2/3 dC/dx = dollars per unit
