Question

F(x) = √(e²x + 2eˣ - 3) - leˣ is equal to Ve2* + 2e* – 3 – he*​. What is the value of l?

A) 1
B) 2
C) -1
D) -2

Answer 1

The value of l in the given equation f(x) = √(e²x + 2eˣ - 3) - leˣ is -1.

Step-by-step explanation:

We are given f(x) = √(e²x + 2eˣ - 3) - leˣ, and we need to find the value of l.

To find the value of l, we can compare the given equation with the given expression: f(x) = Ve2* + 2e* – 3 – he*​. Since both equations are equal, we can equate the corresponding terms.

Comparing the coefficients of eˣ, we get 1 = -l. Solving for l, we find that l = -1, so the answer is C) -1.
