Answer: option 1.

x f(x)
4 log (4) 4 = 1 ... because 4^1 = 4
16 log(4) 16 = 2 .... because 4^2 = 16
64 log (4) 64 = 3 .... because 4^3 = 64
Answer:
y= 7^-t
Step-by-step explanation:
Equation for exponential decay:
An equation represents exponential decay if a term between 0 and 1 is elevated to the independent variable.
In this question:
First option 4 is elevated, so not exponential decay.
Second option:

, thus, the second option represents exponential decay.
Yes it is because 5 5/8 it’s bigger than 5 and 3/6
It is A because you have to divide by a negative one
