Answer 1

To determine the domain of the inverse function \( g^{-1}(x) \), we need to know the range of the original function \( g(x) \). The range is made up of the outputs of \( g(x) \).

From the given values:

• When \( x = -8 \), \( g(-8) = 0 \)
• When \( x = -7 \), \( g(-7) = 8 \)
• When \( x = 6 \), \( g(6) = 4 \)
• When \( x = 10 \), \( g(10) = -5 \)
• When \( x = 15 \), \( g(15) = -7 \)

The outputs (or the values of \( g(x) \)) are:

• \( 0 \)
• \( 8 \)
• \( 4 \)
• \( -5 \)
• \( -7 \)

Thus, the range of \( g(x) \), which corresponds to the domain of \( g^{-1}(x) \), is: \[ {-7, -5, 0, 4, 8} \]

Therefore, the correct option that represents the domain of \( g^{-1}(x) \) is: {−7,−5,0,4,8}.
