Question 949582
Defined for all real values of x;
Approach y=0 to the left, infinity to the right;
DOMAIN:  All real values of x.
RANGE:  Real values greater than 0.


INTERCEPTS?
Set x=0 for each function.  What is y?


Setting y=0 to solve for x-intercept produces no result.  Your two exponential functions never intersect the x-axis.
