Which is an exponential growth function f(x)=6(0.25)x
f(x)=0.25(5.25)x

Second Option

Step-by-step explanation:

The exponential growth functions have the following form:

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:

The correct answer option is B. .

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. :

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. :

Positive numbers with base of the exponent greater than 1, therefore it is an exponential growth function.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
