  4. D \(1011\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(1011\)

Step-by-step Solution

Detailed explanation

\(f(x)=\frac{4^x}{4^x+2}\) \(f(x)+f(1-x)=\frac{4^x}{4^x+2}+\frac{4^{1-x}}{4^{1-x}+2}\) \(=\frac{4^x}{4^x+2}+\frac{4}{4+2\left(4^x\right)}\) \(=\frac{4^x}{4^x+2}+\frac{2}{2+4^x}\) \(=1\) \(\Rightarrow f(x)+f(1-x)=1\)…
