Answer:
1. B. a=14, b=2
2. D. a=1, b=1.4
Step-by-step explanation:
The exponential growth function can be represented as
[tex]y=a\cdot b^x,[/tex]
where b is the growth factor.
1. When the function has equation
[tex]g(x)=14\cdot 2^x,[/tex]
then
[tex]a=14,\\ \\b=2[/tex]
The initial amount is the value of the function at x=0:
[tex]g(0)=14\cdot 2^0=14\cdot 1=14[/tex]
The growth factor is b=2
2. When the function has equation
[tex]f(t)=1.4^t,[/tex]
then
[tex]a=1,\\ \\b=1.4[/tex]
The initial amount is the value of the function at t=0:
[tex]f(0)=1.4^0=1[/tex]
The growth factor is b=1.4
