The range of the function is;
b) For this function, we can see the domain from -2 to 2
In interval notation, this is;
The range of this function as we can see is from 0 to infinity
We have the interval notation as;
c) For this function, we have;
Domain starts from -4 and extends toward infinity
We have this as;
For the range, we have this as;
