15 Here are six graphs.

Six sketch graphs labelled A to F. A: reciprocal curve in the first and third quadrants. B: cubic falling from top left to bottom right, flat at the origin. C: two branches above the x-axis either side of the y-axis, rising steeply near the y-axis. D: two branches below the x-axis either side of the y-axis. E: reciprocal curve in the second and fourth quadrants. F: cubic rising from bottom left to top right, flat at the origin.

Complete the table below with the letter of the graph that could represent each given equation.

Write your answers on the dotted lines.
