y = (1/2)^x
y = -2^x
The equations is notexponential is y = .
Calculating the exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function. Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread.
The standardform of exponential form is
f(x) =
1. y =
Thus is not Exponential function because any power of 1 result to only 1.
2. y =
This is Exponential Function as it has initial value 0.5.
3. y =
This is Exponential Function as it has initial value -2.

Using the combination formula, it is found that the students can be selected in 105 ways.
The order in which the students are selected is not important, hence the combination formula is used to solve this question.
The number of possible combinations of x elements from a set of n elements is given by:
In this problem, two students are selected from a set of 15, hence the number of different orders is given by:

Answer:
C.369
Step-by-step explanation:
one year is 12 months and he took out 30.75 every month so
30.75 multiplied by 12 is 369
its C
Answer:
Kevin earns $122.5 a month.
Step-by-step explanation:
First we sum, 212.5 + 32.5 = 245 which is twice the amount of $ Kevin makes in a month, so we divide by 2, 245/2 which is 122.5
