Prac%ce Problems 11.1.13 Problem 1
a. What are the Independent and Dependent Variables? What are the units of each variable? IV = Units of IV = DV = Units of DV = b. Describe and explain the rela%onship between the units of the rate of change. c. What is the correla%on of the two func%ons; f1(x) and f2(x)? Ex: Posi%ve, Nega%ve, Zero Slope, Undefined d. What are the x-‐intercepts of f1(x) and f2(x)? Solve algebraically. Explain if these are reasonable values. x-‐int of f1(x) = x-‐int of f2(x) = e.

Prac%ce Problems 11.1.13 Problem 2
a. What are the Independent and Dependent Variables? What are the units of each variable? IV = Units of IV = DV = Units of DV = b. Describe and explain the rela%onship between the units of the rate of change. c. The first func%on is p=2.5n. What is the second func%on in slope-‐intercept form? d. What is the ini%al value of the second func%on? e. What are the x-‐intercepts of f1(x) and f2(x)? Solve algebraically. Explain if these are reasonable values. x-‐int of f1(x) = x-‐int of f2(x) = f.
