Answer:
Option A (0,a)
Explanation:
we know that
![f(x)=a(b^(x))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2slaif8k8lw5gb6yadst4ilvo7awjvuexm.png)
Is a exponential function
where
a is the initial value
b is the base
Remember that
The initial value is the value of the function when the value of x is equal to zero (y-intercept)
therefore
For x=0
![f(0)=a(b^(0))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/6dyh7jv2r2t5t8vnrjnxpt9lsnooq1111m.png)
![f(0)=a(1)=a](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tmvrsn9cm6xgrujs6jlp8tfr480yj5syu1.png)
The y-intercept is the point (0,a)
