  1. A \(\left( { - \frac{1}{3},\frac{4}{3}} \right)\)
  2. B \(\left( {\frac{3}{4},\frac{7}{4}} \right)\)
  3. C \(\left( { - \frac{1}{4},\frac{1}{2}} \right)\)
  4. D \(\left( {\frac{1}{4},\frac{3}{4}} \right)\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\left( {\frac{3}{4},\frac{7}{4}} \right)\)

Step-by-step Solution

Detailed explanation

\({x^2} + 4x = 5\) \( \Rightarrow x = - 5,x = 1\) \( \Rightarrow P\left( {1,2} \right)\) Tangent at \(P\) is \(y = x + 1\) \(\left( {\frac{3}{4},\frac{7}{4}} \right)\) lies on this.
