To make the game last longer, use more than 24 questions. The use of the vertical line test and mapping diagrams are also discussed. 11.3 Writing Relationships from Slope Triangles. C. a u-shaped line. By convention, graphs are typically constructed with the input values along the horizontal axis and the output values along the vertical axis. For every x value, there is a unique y value. Every math classroom needs a number line! To determine if a graph represents a function. We have to check whether the vertical line drawn on the graph intersects the graph in at most one point. Students use an applet to explore the vertical line test on a … There is not enough information to determine if the graph is a function. It is a function, since a vertical line will cross the graph at more than one point. In the activity, children will have to sort triangles into categories depending on the size of the angles. Alternatively, a spirit level that exploits the buoyancy of an air bubble and its tendency to go vertically upwards may be used to test for horizontality.
