Identify the type of function represented by f(x)=3•(0.5)^x
a. increasing linear
b. exponential decay
c. exponential growth
d. decreasing linear

B. Exponential decay

Step-by-step explanation:

Let x = independent variable  .

The linear function is given by : , where m= slope or rate of change of y with respect to x and c = constant represents the initial value of function.

When m < 0 , then we call it decreasing linear function

When m > 0 , then we call it decreasing linear function or equation.

When m = 0 , then we call it constant function .

The exponential function is given by : , where a is the initial value of function and b is the multiplicative growth / decay rate.

When b<1 , then we call it exponential decay function.

When b>1 , then we call it exponential growth function.

Given function:

This function is exponential decay function where b= 0.5<1 .

Hence, the correct answer is B. Exponential decay.

it is 10.6 according to my calculations

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
