In this question, we need to draw the graphs of the functions, mode y is equals to x and y square is equal to x square.
00:11
We need to draw these two graphs and we need to tell why they are not the graph of functions.
00:16
So as we know that, if we go for this graph, it means we will write that y is equal to, or we can say that if mode y is equals to x, it means x is always positive.
00:32
X is always positive so for this what we will do we will just draw a vertical line and that will be our let's say y xxas and similarly this will be our x -axis now since x is always positive its graph will be drawn like this first line will be y is equals to x type and in the same way below x -axis also this line will look like this this angle is also 45 degrees and this angle is also 45 degrees.

As we can see that at a single value of x, we can get two different values of y.
01:15
One is this one and another maybe this one.
01:20
Since we are getting the two values of y at a single value of x, so it is not a function.
01:26
Since we are getting two values of function, a single value of input...
