My question is, on problem #2 of the assigned worksheet you only want us to graph each equation once, Right? The second (last) paragraph for this problem is just clarification, I hope, for the preceeding statement.
Good question. Do try to include a copy of the problem, so when I post my answer it will be clear exactly which problem you are asking about. Another reason is so I'll know exactly what you are asking about.
The problem I think you are asking about asks the following:
Determine the location of the vertex of each of the following quadratic functions:
y = x^2 + x + 1
y = x^2 + 2x + 1
y = x^2 + 3x + 1
y = x^2 + 4x + 1
y = -2 x^2 + 4x + 3
Sketch a graph for each function showing 3 points: the vertex and the points 1 unit to the right and 1 unit to the left of the vertex.
Sketch the graph of each function, based only on the 3 points you have sketched and your knowledge that the graph is a parabola.
To clarify:
You are asked to first sketch only 3 points for each function.
You are then asked to sketch the graph based on just these 3 points.
