Question
Question: The line \(x + y = 2\) is tangent to the curve \(x^{2} = 3 - 2y\) at its point...
The line x+y=2 is tangent to the curve x2=3−2y at its point
A
(1, 1)
B
(–1, 1)
C
(3,0)
D
(3, – 3)
Answer
(1, 1)
Explanation
Solution
Given curve x2=3−2y
diff. w.r.t. x, 2x=−dx2dy; dxdy=−x
Slope of the line = – 1
dxdy=−x=−1; x=1
∴y=1 point (1, 1)
