Q. 8

Mark the correct alternative in each of the following:

The equation of the curve whose slope is given by x > 0, y > 0 and which passes through the point (1, 1) is

A. x2 = y

B. y2 = x

C. x2 = 2y

D. y2 = 2x

Answer :

Slope of the curve is given by

By Variable separable

Integrating both sides

log x + log y = log xy

-- (1)

Since curve passes through the point (1, 1), we get



Putting value of C in (1) we get,


Squaring both sides

x2 = y
