There is a question when deciding to find domain of the following functions.
00:05
Part a, fx is 3x plus 500 root divided by x minus 1.
00:14
So, there would be two parts.
00:15
First is part square root.
00:19
So, square root is defined only when we have non -negative quantities or non -negative numbers in under the square root.
00:31
So, 3x plus 5 greater than 5, so x greater than minus 5 by 3.
00:37
And this is the denominator which must not be equal to 0.
00:42
X minus 1 cannot be equal to 0.
00:44
X cannot be equal to 1.
00:46
So, if you draw a number line, this is minus 5 by 3, this is 1...
