hope this helps
Step-by-step explanation:
exponential decay functions are written in the form :
![y=ab^{x}](https://tex.z-dn.net/?f=y%3Dab%5E%7Bx%7D)
where b is less than 1
if we look at the 3rd choice and consider the term on the right.
![(8/7)^{-x}](https://tex.z-dn.net/?f=%288%2F7%29%5E%7B-x%7D)
= ![(7/8)^{x}](https://tex.z-dn.net/?f=%287%2F8%29%5E%7Bx%7D)
If we compare this to the general form above,
b = 7/8 (which is less than 1)
hence the 3rd choice is correct.
Answer:
I did the whole thing
Step-by-step explanation:
How you do them is you just take each number, and multiply by the number that both fractions can multiply into. I showed how in the picture.
