Write an equation that models the following situation:
Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

• y=6(0.14)^x

• y=6(1+14)^x

• y=6(1.14)^x

• y=6(0.86)^x

Identify the y-intercept (initial value) of the function f(x)=2(4)^x.

• 2

• 4

• (2)^x

• 8

The number of people with the flu during an epidemic is a function, f, of the number of days, d, since the epidemic began. The equation f(d) = 50·(3/2)d defines f. How many people had the flu at the beginning of the epidemic? Explain how you know.

• 2

• 3

• 50

• 3/2

The number of people with the flu during an epidemic is a function, f, of the number of days, d, since the epidemic began. The equation f(d) = 50·(3/2)d defines f

How quickly is the flu spreading?

• (2/3) per day

• (3/2) per day

• 50·(3/2) per day

• 50 per day

The number of people with the flu during an epidemic is a function, f, of the number of days, d, since the epidemic began. The equation f(d) = 50·(3/2)d defines f.

What does f(3.5) represents in this situation?

• Days people are sick with the flu

• Amount of people that are sick with the flu

• Days since the epidemic began

• Initial Value

The number of people with the flu during an epidemic is a function, f, of the number of days, d, since the epidemic began. The equation f(d) = 50·(3/2)d defines f

What does represent f(0)?

• Initial Value

• People that are sick after 10 days

• People that are sick after being healthy

• Number of days since the epidemic began
