Answer:
See below for answers
Step-by-step explanation:
If [tex]f(x)=x^{2}[/tex] and [tex]g(x)=\sqrt{x}[/tex], then:
[tex](f+g)(14)=f(14)+g(14)=14^{2} +\sqrt{14} =196+\sqrt{14}[/tex]
[tex](f+g)(18)=f(18)+g(18)=18^{2} +\sqrt{18} =324+3\sqrt{2}[/tex][tex](f+g)(-16)=f(-16)+g(-16)=(-16)^{2} +\sqrt{-16} =256±4i[/tex]
