A puppy weighs 2.0 pounds at birth and 3.5 pounds two months later. If the weight of the puppy during its first 6 months is increasing at a rate proportional to its weight, then how much will the puppy weigh when it is 3 months old?

• 4.2 Pounds

• 4.6 Pounds

• 4.8 Pounds

• 5.6 Pounds

• 6.5 Pounds

Population y grows according to the equation dy/dx=ky, where k is a constant and t is measured in years. If the population doubles every 10 years, then the value of k is:

• 5.000

• 3.322

• 0.301

• 0.200

• 0.069

Which functions below will have the same slope field? (choose all that apply)

• y = x² - 3

• y = x² + 4

• y = 2x - 5

• y = 2x²
