Answer:
Option A (0,a)
Step-by-step explanation:
we know that
[tex]f(x)=a(b^{x})[/tex]
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
[tex]f(0)=a(b^{0})[/tex]
[tex]f(0)=a(1)=a[/tex]
The y-intercept is the point (0,a)
