The equation in 1, after rearranging, can be considered y as a function of x or x as a function of y.
2. expresses x as a function of y and
3. expresses y as a function of x.
I would say that they are all functions, but your teacher may have other ideas.
can you please help me understand relations and functions.
Like how to figure out if an equation is a function or not a funcion.
for example:
1) 3x+2y=6,
2) x=y^2+2
and
3) y=square root of 1-x
thank you
