Answer:
1. B. a=14, b=2
2. D. a=1, b=1.4
Explanation:
The exponential growth function can be represented as
![y=a\cdot b^x,](https://img.qammunity.org/2020/formulas/mathematics/high-school/s1yjp4hmnukmnumc1lqcaw0jc7hss6nafn.png)
where b is the growth factor.
1. When the function has equation
![g(x)=14\cdot 2^x,](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1a08t25r9dcyremee4zt65b0vugjiknobq.png)
then
![a=14,\\ \\b=2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ucfu0xm2lxwtoay7pcfbl6kngnfmjt7pqh.png)
The initial amount is the value of the function at x=0:
![g(0)=14\cdot 2^0=14\cdot 1=14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mh94vyv5e5gsgj2tbtlxqj0kqqivrlzxdy.png)
The growth factor is b=2
2. When the function has equation
![f(t)=1.4^t,](https://img.qammunity.org/2020/formulas/mathematics/middle-school/83d15f1z1yj4q30h4azocec8yhnamgzj5w.png)
then
![a=1,\\ \\b=1.4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/k9rob2ijb9jcxji21ej7xbd21bhbzubqvo.png)
The initial amount is the value of the function at t=0:
![f(0)=1.4^0=1](https://img.qammunity.org/2020/formulas/mathematics/middle-school/lnkm0ze3xd0ht0i23xx4ckfrc88uy3sjr3.png)
The growth factor is b=1.4
