16. Match each graph to the correct equation. [2]

The first one has been completed for you.

Diagram: five graphs on the left and five equations on the right. The first graph, a vertical line through x = 2, is joined by an arrow to x = 2. The other graphs are: a U-shaped parabola with minimum at (0, -1) crossing the x-axis at -1 and 1; a straight line with positive gradient crossing the y-axis at 1 and the x-axis at -1; an upside-down parabola with maximum at (0, 1) crossing the x-axis at -1 and 1; a straight line with negative gradient crossing both axes at 1. The equations, in order, are x = 2, y = x + 1, y = 1 - x squared, y = 1 - x and y = x squared - 1
