ILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST (and correctly ofc)

Answer:
y = 3 (4)^x
Step-by-step explanation:
quadruples means multiplies by 4
This equation is in the form
y = ab^x where a is the initial amount and b is the amount we multiply by
y = 3 (4)^x
Answer:
B
Step-by-step explanation:
The exponential model is of the form
y = a[tex]b^{x}[/tex]
where a is the initial amount and b the growth rate
Here a = 3 and b = 4 , then
y = 3 [tex](4)^{x}[/tex] → B
