Answer: Second Option
[tex]f(x)=0.25(5.25)^x[/tex]
Step-by-step explanation:
The exponential growth functions have the following form:
[tex]f(x) = a(b)^x[/tex]
Where a is the main coefficient, b is the base and x is the exponent.
For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function
Among the options given, the only function whose base is greater than 1 is the second option:
[tex]f(x)=0.25(5.25)^x[/tex]
Answer:
The correct answer option is B. [tex] f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x [/tex].
Step-by-step explanation:
If the numbers are positive along with the base of the exponent which must be greater than 1, then it an exponential growth function.
1. [tex]f(x)=6(0.25)^x[/tex]:
Here the numbers are positive but the base of the exponent is 0.25 which is less than 1 so it is not an exponential growth function.
2. [tex] f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x [/tex]:
Positive numbers with base of the exponent greater than 1, therefore it is an exponential growth function.
