Hello, let's have a look at the question.
00:02
So the question state, find the domain of each function.
00:06
If the answer is all real numbers, enter r below.
00:10
So now first of all in the a part, we have that fx is equals to 1 upon 1 plus e to the power x.
00:20
Now here to find the domain of the given function, we will take that 1 plus e to the power x is equals to 0.
00:30
Now this implies that e to the power x is equals to minus 1, which cannot be possible.
00:37
That is e to the power x can't be negative 1.
00:42
So therefore we can say the domain of the function will be real numbers that is r.
00:50
Now for the b part, we have that fx is equals to 1 upon 1 minus e to the power x...
