For f(x) to be a function, the value of x should not be repeated. That is no x value can be more then once.
So the required table is

And for g(x) , not to be a function, we have to repeat x value that is

The equation of a cirecle with radius r and center at (h,k) is
(x-h)^2+(y-k)^2=r^2
r=10
center=(-2,-4)
(x+2)^2+(y+4)^2=10^2
(x+2)^2+(y+4)^2=100
(x,y)
sub given points (or use TI) and see if you get a true statmeent
