In the exponential function , if , the output gets smaller as gets larger. In this case, is called an exponential decay function.
let see what is in your case:
a) -> and ; unction is an exponential growth
b) -> and ; unction is an exponential growth
c) -> and ; unction is an exponential
d)-> and ; unction is an exponential growth
so, your answer is:
c) -> and ; unction is an exponential
see its graph:
