No. It's an equation.
" 3x squared - 2 " is a function. As soon as you made it equal to something, you had an equation.
y = 3x = 12y = 12
-9
3x-y=9 y=3x-9
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
1) y - 7y = 36 -6y = 36 y = -6 We know that, y = 3x -6 = 3x x= -2 Conclusion, y= -6, x = -2
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
y=3x+12
6
-2
yes

No.
If you mean: y = 15+3x then it is the function of a straight line equation.
Yes.
If a graph is a function, it will always have y=... or x=... (or anoher letter equals an equation) for example y= 3x-12 is a function
y = 3x = 12y = 12
