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
