Type the correct answer in each box. Write the coordinates in the form (x ). If necessary, use / for the fraction bar(s). D = (-8.25, -5.75)
E
F = (-6.5, -7.5)
G
H = (-4.75,-9.25)
In the diagram, AB is divided into equal parts. The coordinates of point A are
and the coordinates of point/are

Look at x = 4. Note how we can draw a vertical line through 4 on the x axis and this single vertical line crosses more than one point. This means the graph fails the vertical line test, and therefore it is not a function.

A single input (x = 4) leads to more than one output (y = -2 and y = 4 at the same time). A function is only possible if any given input in the domain leads to exactly one output.
