The range of the function \(f(x)=\frac{x-3}{5-x}, x \neq 5\) is

  1. A \(\mathrm{R}-\{1\}\)
  2. B \(\mathrm{R}-\{-5\}\)
  3. C \(\mathrm{R}-\{5\}\)
  4. D \(\mathrm{R}-\{-1\}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\mathrm{R}-\{-1\}\)

Step-by-step Solution

Detailed explanation

(A)
We have \(y=\frac{x-3}{5-x}\) \(\therefore 5 y-x y=x-3 \Rightarrow x+x y=5 y+3\) \(\therefore x=\frac{5 y+3}{1+y}\) Hence Range \(=R-\{-1\}\)
