In this question it is given that match the following functions with their contour plot.
00:07
Now four functions are given.
00:10
First function is given as fxy is equals to y minus x square.
00:18
Second function is given as f xy is equals to x minus y square.
00:25
Third function is given as f xy is equal to x plus y square.
00:32
And the fourth function is given as f xy is equal to y plus x square so one by one we will see so for the first one we will just equate this f xy to zero so we'll be getting y minus x square equals to zero it means y is equals to x square so basically this graph is of the format x square equals to 4a y which will be opening upward so opening upward means this graph so this is the correct option is d.
01:04
Next for the second one, for the second graph, if we equate f xy to 0, it means x is equals to y square or x minus y square equals to zero means x is equals to y square because since it is the of the format y square equal to 4a x.
01:23
So it will be opening right word and which graph is opening right right word is a.
01:28
So for this the correct match will be.
01:32
Now for the third part, that is f xy equals to 0...
