Find the Domain (4x-1)/(2x+1)

Problem

(4*x−1)/(2*x+1)

Solution

1. Identify the condition for the domain of a rational function, which requires that the denominator cannot be equal to zero.

2. Set the denominator expression equal to zero to find the excluded value of x

2*x+1=0

3. Solve the equation for x by subtracting 1 from both sides.

2*x=−1

4. Divide both sides by 2 to isolate x

x=−1/2

5. State the domain as all real numbers except for the value that makes the denominator zero.

Final Answer

Domain: *{x|x∈ℝ,x≠−1/2}
