Question

The function below shows the number of students of a school who enrolled for salsa classes. Let f(x) represent the total number of students who enrolled for the classes after x years.

f(x) = 10(1.18)^x

The average rate of change in the number of students who enrolled for salsa classes from the second to the fifth year is ________students per year.

Round your answer to the nearest whole number.

Answer 1

f(5) = 10(1.18)10

f(5) = 10 * 5.9

f(5) = 59

---

f(2) = 10(1.18)2

f(2) = 10* 2.36

f(2) = 23.6

f(b) - f(a)/b-a

59 - 23.6/5-2

35.4/3 = ?

Answer 2

u so dumb it's ^x

Answer 3

Dumbpellet... put the damn ^ -.-

Answer 4

I did u tard

Answer 5

In the second year, no of students who enrolled class is

f(2) = 10 * 1.18^2 = 13.924 ~ 14 (students)

Similarly, in fifth year,

f(5) = 10 * 1.18^5 = 22.87 ~ 23 (students)

The average rate of change from 2nd to 5th year is

\[\frac{f(5)-f(2)}{5-2} = 3\]

Average rate of change is 3 students per year
