-4

200

Is the following a function? Why or why not? (Note: you must explain why or why not to get the points for this problem) 

(1,2) (2,3) (3,4) (4,5)

Yes because each x value has one and only one y value.

The following points are on a line: (4, 2) (4, 3) (4, 4) Is the line a function? Why or why not? You must correctly answer why or why not to get credit for this question.
no, because for the value x = 4 there is more than one possible y value.

5.98 x 10 -6

400
Is the equation x = 6 linear? Why or why not? Is it a function? Why or why not? Answer all parts of above for credit for this question.
Yes it is linear because it forms a straight line (vertical) No it is not a function because there is more than one y value when x = 6.
400

What is a nonlinear relationship?

When the rate of change is not constant, the graph is not straight, or the equation cannot be written in slope-intercept form (y=mx+b)
