The standard form equation: x2+y2=16, what is the general form for this equation

The equation of the circle with radius 4.

Step-by-step explanation:

The given equation is .

General equation of the circle is

where: is the centre of the circle and is the radius.

Here the centre is and radius is .

Therefore this is the equation of the circle with centre and radius .

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
