The domain of the function \( f(x) = \log_{5}(x+2) \) consists of all values \( x \) for which the expression inside the logarithm is positive. Since \( x + 2 > 0 \), we have \( x > -2 \). Therefore, the domain is \( (-2, \infty) \). As for the range, logarithmic functions can produce all real numbers as outputs. Thus, regardless of the base, \( f(x) \) can take any value from negative infinity to positive infinity. Hence, the range is \( (-\infty, \infty) \).
