For function A it is exponential for function B it is linear for function C it is exponential.
What is a function?
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Linear would be if the change between the x and y's are similar:
Function A:
9.252 - 6.083 = 3.169
14.07 - 9.252 = 4.81A
21.4 - 14.07 = 7.33
The differences are different so it is exponential.
Function B
14-7 = 7
21 - 14 = 7
28 - 21 = 7
The differences are the same so this is linear.
Function C
4-16 = -12
1-4 = -3
0.25 - 1 = -0.75
The differences are different so this is exponential.
Therefore for function A, it is exponential for function B it is linear for function C it is exponential.
