1.	Let f be a real valued function satisfying f(xy)=f(x)−f(y) and ltx→0f(1+x)x=3. Then find the area bounded by the curve y=f(x), the y-axis and the line y=3 in sq units
Answer» Let f be a real valued function satisfying $f (\frac{x}{y}) = f (x) - f (y)$ and $l t x \to 0 \frac{f (1 + x)}{x} = 3$ . Then find the area bounded by the curve y=f(x), the y-axis and the line y=3 in sq units
