Hint:
Domain of f(x) is the set of all real value of x.
The minimum value of f(x) is 3. So, the range of the function is [3 , ∞).
The minimum value of f(x) is 3. So, the range of the function is [3 , ∞).
The correct answer is: D : (- , ) , R : (3 , )
To find the domain and range of f(x) = |2x - 1| + 3
Hence, the domain of f(x) is the set of all real value of x and the range is [3,∞).
