Question

What’s the answer??(SOMEONE PLEASE HELP ME)

Answer 1

We know that :

If f(x) and g(x) are Two Functions Defined under same Domain, then Composite Function : (f o g)(x) = f(g(x))

Given : f(x) = $\frac{2}{x + 3}$ and g(x) = $\frac{1}{2x}$

⇒ (f o g)(x) = f(g(x))

⇒ $(f\;o\;g)(x) = f(\frac{1}{2x})$

⇒ $(f\;o\;g)(x) = \frac{2}{\frac{1}{2x} + 3} = \frac{4x}{1 + 6x}$

1st Option is the Answer
