f (x) = 2/3 x + 2
f(x) = x + 1, to reflect this across the y-axis you need to reverse all the x values. Essentially, what this means is that, you rewrite f(x) as f(-x) making the function, -x + 1.

1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
1) Solve the equation for the desired variable. 2) Write it in function notation. For example, if y = 2x + 3, it is already solved for "y"; just rewrite it as f(x) = 2x + 3.
f (x) = 2/3 x + 2
y = -x-2
If you mean: x-2y = 8 then it is y = 0.5x-4.
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
It would be rewritten as y=(2/5)x+3
5x + 5y = 19x = 3.8 - yory = 3.8 - x
Rewrite is a record function, a dvd player is just that, a player.
You need to give an example of the rule and the function you want.
You need it in the form f(x)= ... (whatever your equation happens to be). i.e get the equation in the form y=... Then swap the 'y' for 'f(x)'. Simple.
