Answer:
Exponent function, y = ab
If x as exponent of any number then it would be exponent function.
Exponent function types:
(i) Growth
(ii) Decay
If value of 0<b<1 then function is decay.
If value of b>1 then function is growth.
We will compare the function and to find value of b
3(1.5) = ab
b = 1.5 > 1
Explanation:
exponential growth
