A quality control technician is inspecting a manufactured part with an edge that follows the shape of a horizontal parabola (a curve that opens to the side). When plotting this shape on a coordinate grid, why is it determined that the graph fails the vertical line test?

A technician at a manufacturing facility is examining data plots of different machine components to determine if they represent mathematical functions. Match each component's graphed shape with the correct conclusion based on the vertical line test.

A drafting technician is reviewing a blueprint that includes a component's edge shaped like a horizontal parabola (a curve that opens to the side). True or False: This shape represents a mathematical function because it passes the vertical line test.

Quality Control and the Vertical Line Test

A technical designer is evaluating a graph of a sideways curve, also known as a horizontal parabola. To determine if this graph represents a mathematical function, the designer applies the vertical line test. The graph is determined not to be a function because at least one vertical line can be drawn that intersects the curve at ____ distinct point(s).
