Answer:
Step-by-step explanation:
Actually, your question isn't very clear, there are two possible ways to this question:
- Find [tex]x[/tex] if [tex]g(x)=-7[/tex] (most likely)
- Find [tex]g(x)[/tex] if [tex]\\x=-7[/tex]
Solution of (1):
[tex]-7=11-x\\x=11+7=18[/tex]
Solution of (2):
[tex]g(-7)=11-(-7)=18[/tex]
