Unit 7 HW 2

Which of the following represents an exponential growth of thirty five percent?

Which function represents an initial population that increases 24% per year where A represents the initial value and x represents time in years?

Suppose four (4) cannonballs were fired into the air and their flightpaths are modeled by four (4) quadratic functions with the following attributes:

Cannonball A: Has vertex point (2,300)

Cannonball B: Represented by the function f(x)=-(x-15)² + 200

Cannonball C:  Represented by the function f(x) = -4(x- 4) (x- 12)

Cannonball D:  Represented by the table to the left:

Assume that the x-axis represnets the ground and f(x) represents the height in feet. Which cannonball went the highest?

                     

• Cannonball 1

• Cannonball 2

• Cannonball 3

• Cannonball 4

• 0.5

• 2.5

• 8

• 10

Which function represents an initial population that increases 32% per year where A represents the initial value and x represents time in years?   

• y = A(0.68)^x

• y = A(1.32)^x

• y = A(1.68)^x

In the equations below, b and c are constants. If b is c minus 1/2 which of the following is true?
