The original function \( f(x) = x^{\frac{1}{2}} \) has a domain of \( [0, \infty) \). However, with the transformation applied in \( m(x) = (x+1)^{\frac{1}{2}} + 2 \), we determine that the smallest value of \( x \) in this function shifts to \( -1 \) because it becomes valid for \( x + 1 \geq 0 \). Thus, the domain of \( m \) is \( [-1, \infty) \). As for the range, the minimum output occurs when \( x = -1 \), giving \( m(-1) = (0)^{\frac{1}{2}} + 2 = 2 \). Since the function can increase indefinitely as \( x \) grows, the range of \( m \) is \( [2, \infty) \). So, for the final answer: domain: \( [-1, \infty) \) range: \( [2, \infty) \)
