Which of the following curve is represented by y^(2)=1-x? |
|
Answer»
Since, the power of y is even, therefore, curve is symmetrical about x-aixs. Putting x = 0, `y=pm1` Putting y = 0, x = 1 Therefore, the curve passes through the points (1, 0), (0, 1) and (0, -1) Then CLEARLY, the equation `y^(2)=1-x` REPRESENTS the graph. |
