Question

Please please help me with this problem

Answer 1

Answer:

See below for answers

Step-by-step explanation:

If $f(x)=x^{2}$ and $g(x)=\sqrt{x}$, then:

$(f+g)(14)=f(14)+g(14)=14^{2} +\sqrt{14} =196+\sqrt{14}$

$(f+g)(18)=f(18)+g(18)=18^{2} +\sqrt{18} =324+3\sqrt{2}$$(f+g)(-16)=f(-16)+g(-16)=(-16)^{2} +\sqrt{-16} =256±4i$
