The number of mosquitoes at the beginning of the summer was 4,000. In 4 months, there were 9,765 mosquitoes. Write an exponential model to represent this situation? Round the base to three decimal places.

• y = 4000(1.2)^x

• y = 9765(1.240)^x

• y = 4000(1.240)^x

• y = 5765(1.24)^x

• f(x) = 35(0.95)^x

• f(x) = 36(0.05)^x

• f(x) = 35(1.05)^x

• f(x) = 36(1.5)^x

Use the graph to help!

• Domain: (−∞ < x < ∞)

  Range: (0 < x < ∞)

• Domain: (−∞ < x < ∞)

  Range: (1 < x < ∞)

• Domain: (−2 < x < ∞)

  Range:(0 < x < ∞)

• Domain: (−∞ < x < ∞)

  Range: y < 0

What is the y-intercept of the function and the horizontal asymptote?

• y-intercept: y= 4; asymptote: y = 1

• y-intercept: y= 3; asymptote: y = 0

• y-intercept: y= 2; asymptote: y = 0

• y-intercept: y= 0; asymptote: y = 0
