Answer:
Exponential Growth
Explanation:
Given:

We are given a function. x as exponent of 1.5
Exponent function,

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


The function is exponential growth function.
