Answer:
The limit of the range is y>-100.
Step-by-step explanation:
Given : The domain is all real numbers, for the function 
To find : what is the limit of the range for the function?
Solution :
The function we have given is an exponential function.
The domain of the function
is all real number.
i.e, ![D=(-\infty,\infty),[x|x\in\mathbb{R}]](https://tex.z-dn.net/?f=D%3D%28-%5Cinfty%2C%5Cinfty%29%2C%5Bx%7Cx%5Cin%5Cmathbb%7BR%7D%5D)
Range is defined as the set of value that corresponds with the domain.
Taking, 
Function approaches to -100
Taking, 
Function approaches to 
Therefore, The range of the function is defined as
![R=(-100,\infty),[y|y>-100]](https://tex.z-dn.net/?f=R%3D%28-100%2C%5Cinfty%29%2C%5By%7Cy%3E-100%5D)
So, The limit of the range is y>-100.
