The focus of the parabola is (1, 1) and the tangent at the vertex has the equation x + y = 1. Then which of the following is incorrect
- equation of the parabola is (x – y)2 = 2 (x + y – 1)
- equation of the parabola is (x – y)2 = 4 (x + y – 1)
- the co-ordinates of the vertex are \(\left(\frac{1}{2}, \frac{1}{2}\right)\)
- length of the latus rectum is 2\(\sqrt{2}\)
Answer
