Answer:
The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12
Step-by-step explanation:

6 + 21 = 27 (Add six ones)
60 + 21 = 81 (Add six tens)
I hope this helps:)
I'm sorry if it doesn't:(
Using it's concept, the range of the given exponential function is:
C. 0 < y ≤ 46638.
<h3>What is the range of a function?</h3>
The range of a function is the set that contains all possible output values for the function.
In this problem, the function is:
y = 46,638(0.78)^x.
It is an exponential function with initial value 46,638 and rate of change 0.78. Exponential functions that are not shifted down, such as this one, are never negative nor zero, hence the range also has the restriction y > 0, and is given by:
C. 0 < y ≤ 46638.
