If all the graphs above have equations with form y=ab^x

Given that all the graphs have the equation :
[tex]y=ab^x[/tex]Where a is the starting value and b is the constant multiplier.
Solution
Largest value of b = G
Smallest value of b = B
Largest value of a = R
Explanation
Exponential functions behave as follows:
The larger the base of our exponential function, the faster the growth
