Find an equation that represents y as a function of x.

Which one would this one be:

a) y=3x b) x= 10 c) x=0 d) x=3

I believe this one is a, what do you think?

Your guess is correct.
But do you really understand WHY?

 

[RicanGurl]

yes

because when they say F(x) , that is the function, there for y would be the function, x can't be the function

More precisely: A is an equation that represents y as a function of x.

You have x as your independent variable and y as your dependent variable. y depends on the value of x
