1) Exponential functions are given in this form:
For these questions let's focus on these two topics:
If x>0 then they are increasing, if x<0 then they are decreasing ones.
If the base is negative, a<0 then the graph will be traced below the x-axis.
Check the each and their corresponding function based on these pieces of information.
2) Check them below
