Interpreting that function as y=x2+2x+1, the graph of this function would be a parabola that opens upward. It would be equivalent to y=(x+1)2. Its vertex would be at (-1,0) and this vertex would be the parabola's only zero.

You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.

Yes, that is a shifted tanX graph, just as you would shift any graft.

-2x plus 3y equals 1
y=2x means that the line on the graph will travel through the coordinates (0,0) (2,1) (4,2) (6,3) etc. Basically it will go up 2x's for every 1y.y=2x is a linear function.

y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)
