Both. If you look at it like this: y=41-x
you say x is independent and y is dependent of x (i.e. y is a function of x)
For x=41-y
you say y is independent and x is dependent of y (i.e. x is a function of y)
The [ 2x + 1 ] represents a function of 'y' .
Well, f(x) = 6x + 9 is a function of x {it passes the vertical line test}. but y = 6x + 9 is an equation {linear equation of two variables}
no
You need another equation.
It is an equation and the value of x works out as 88
No, that is a equation.
a function
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
Yes.
The [ 2x + 1 ] represents a function of 'y' .
Yes it is a function. In standard form it is y=x-4.
y=3x+12
A linear relationship. Added: And a function.
It is the equation of a straight line
It is an equation in two variables, c and g.
If you mean: y = 15+3x then it is the function of a straight line equation.
No. That is an equation. A fraction can be plugged into it for x or y. An example of a fraction is 1/2
