Yes.
Yes.
Y = 2X + 8 is a linear function of the form, Y = mX + c. A line.
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
Yes.
The [ 2x + 1 ] represents a function of 'y' .
If Y equals 2X - 2X - 24, then there is one root, and it is -24. The two 2X's cancel each other out.
Yes.
The expression in the question "y -2x" is not a function.
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
