We have given here x equals to y square plus 4.
00:06
So for this we have to make the points here x equals to y square plus 4.
00:14
Now we have to find the points here.
00:20
So these are the point x and y put x equals to 0.
00:25
Putting x equals to 0 that is y square equals to minus 4.
00:29
So this is undefined.
00:30
I square quantity cannot be negative so this is undefined so now put x equals to minus 4 that means here minus 4 and 4 or any of these so put i am putting 4 so this will be 0 then this will be effectively 4 y square plus 4 minus 4 this will be 0 equals to y square that means y square equals to 0 and if i am putting here 8, x equals to 8, put x equals to 8, then y square plus 4.
01:09
So y square will be 4, that means y equals to plus and minus 2.
01:15
Also we can take any of this point.
01:19
So i am putting here x equals to this is 20.
01:25
So 20 equals to y square plus 4, that means y square equals to 16.
01:31
That means y equals to plus and minus 4...
