Hi, first we talk about domain.
00:03
So what is domain of function? domain is all values of x for which the function is defined, right? that's how we define the domain.
00:13
So we're given here the function gx is equal to gx is equal to square root 5x plus 35.
00:24
So we have square root 5x plus 35.
00:31
This we have.
00:32
This is going to be gx here.
00:33
So, we're going to find domain of this given function.
00:38
So how to find out that so far? in a square root, if we look at the square root function, so we just take here we have for, let's say a simple square root function graph, we just throw it out here.
00:54
Let's say y equal to root x.
00:55
If i just draw that for x, so y is equal to root x.
01:02
So perhaps it's like that.
01:04
If you see here, the y called root x, we have domain is coming out to be x squared and equal to 0.
01:09
Right axis greater than equal to 0.
01:11
Not here, it is given as score out 5x plus 35...
