Let’s break it down! To find \( g(0) \), substitute \( x = 0 \) into \( g(x) = x + 2 \). So, \( g(0) = 0 + 2 = 2 \). Now for \( f(-2) \), substitute \( x = -2 \) into \( f(x) = x^{2} - 5 \). Thus, \( f(-2) = (-2)^{2} - 5 = 4 - 5 = -1 \). Moving on to \( f(0) \), substituting \( x = 0 \) gives us \( f(0) = 0^{2} - 5 = -5 \), which we've already noted! When determining the range of \( g(x) \) with the domain as \(-1\), simply plug in \(-1\). So, \( g(-1) = -1 + 2 = 1 \). The output is one value, thus, the range here is just \( \{1\} \). For \( f(x) \) with a domain of \( 1 \), calculate \( f(1) = 1^{2} - 5 = 1 - 5 = -4 \). The output again is singular, leading to a range of \( \{-4\} \).
