Chapter 3.4, Problem 9QR

Sales v (in thousands of dollars) decreased steadily then increased steadily, as shown in the graph where x is the time in months. This can be modeled by f(x)= 2x– 3 +1 for x>0. y (0, 7) 7. 1 (3, 1) 012 3 4 5 6 * Time (months) 98. Which piecewise definition should be used to find the sales in month 2? A) -2x+4 if x3 D) 2.x-2 if x23 99. Which piecewise definition should be used to find the sales in month 5? A) -2x+4 if x<3 B) -2x+7 if r<3 C) 2.x-5 if x23 D) 2x-2 if x23 100. What are the sales during month 6? A) $3000 B) $6000 C) $7000 D) $10000 Sales (thousands of dollars)

is the point (3,-5) on the graph of function f(x)=3/2x-8? yes, no, impossible to determine

Sketch the graph of f (x) = (x - 2)4 - 1.

A fruit grower determines that the number of bushels of apples produced, f(x)=-0.012x^2 + 1.03x + 2.46. Which graph is an equivalent model for this relationship?
