Given only two variables of a function, explain how to graph one in terms of the other

Question

In this case, explain how to graph D in terms of y.

Answer 1

This would be unlike our typical functions, which are of the form y = mx + b (linear), or y = x² + bx + c. That is you are graphing the value y in terms of x. Here, if you set up your graph, you might put y on the horizontal axis and D on the vertical axis. That would be D in terms of y. You might have D = 12y - 3y² for example. Make sure that D is the variable on one side and y values on the other.
