# Thread: Finding coordinates on a graph.

1. ## Finding coordinates on a graph.

The equation given is y = x^2 (a parabola) and the coordinates given are (0,2) and (1,1). The first part of the problem says to find the coordinates of a point, C, which is near the left tail end of the parabola. But then, the second part of the problem gives these coordinates: (0,b) and (1,1) and then says to find the coordinates of the same point, C, in terms of b.

Can someone explain to me what it means to find the coordinates in terms of b and how to do it?

2. How do the coordinates relate to the equation? (The coordinates are not points on the graph.)

What is meant by "left tail end"? (The quadratic does not end, unless there is more information which was omitted, so there is no "end".)

Is there a picture that goes with this?
