5 Here are six graphs.

Six sketch graphs labelled A to F: A a U-shaped parabola through O; B a cubic with a maximum then a minimum, through O; C a reciprocal-type curve in the second and fourth quadrants; D a reciprocal curve in the first and third quadrants; E a straight line with positive gradient and positive y-intercept; F the curve y = x cubed shape through O

Write down the letter of the graph that could have the equation

(a) \(y = x^3\) (1)
(b) \(y = \dfrac{1}{x}\) (1)
