Answer:
Look at the attachment.
Step-by-step explanation:
a) [tex]x^2+y^2+10x-4y+33=0\\x^2+10x+29=4y-y^2-4\\(y-2)^2=-x^2-10x-29\\y=2-\sqrt{-x^2-10x-29}[/tex]
b) [tex]x^2+y^2+14x-16y+104=0\\x^2+14x+104=16y-y^2\\(y-8)^2=-x^2-14x-40\\y=8-\sqrt{-x^2-14x-40}[/tex]
c) [tex]x^2+y^2+4x-10y+29=0\\x^2+4x+29=10y-y^2\\(y-5)^2=-x^2-4x-4\\y=5-\sqrt{-x^2-4x-4}[/tex]
Graphs are added in the attachment.
