Answer:
3
Step-by-step explanation:
f(x)=a*b^x - is a formula of exponential function
As we know the point (x=0; y=3) lies at the function's  graph.
So we have to put in formula f(x)=a*b^x   x=0  f(x)=y=3
3=a*b^0   (b^0=1) => 3=a*1 => 3=a

All you have to do basically is make up an equation of your own and then plug in the numbers inplace of the variables  while still keeping the equation true.
The answer can be anything from : 8-4= 2+2
And all you had to do was simply plug in numbers to make it true. Hoped i helped!
