The value of ₀^ 1 1 + 2^ x ,dx is _____
Options
- A2
- B2
- C3 2
Correct answer
A. 2
Step-by-step solution
Let I = ₀^ 1 1 + 2^ x , dx Using the property ₀^a f(x) , dx = ₀^a f(a-x) , dx , we get: I = ₀^ 1 1 + 2^ ( - x) , dx I = ₀^ 1 1 + 2^ - x , dx I = ₀^ 2^ x 2^ x + 1 , dx Adding the two equations for I : 2I = ₀^ ( 1 1 + 2^ x + 2^ x 1 + 2^ x ) , dx 2I = ₀^ 1 , dx 2I = I = 2 Answer: 2
