12 Here are six graphs.

Six sketch graphs: A a u-shaped parabola crossing the negative y-axis; B a reciprocal curve in the second and fourth quadrants; C a negative cubic; D a curve in the first and second quadrants symmetrical about the y-axis approaching both axes; E a positive cubic; F a reciprocal curve in the first and third quadrants

Write down the letter of the graph of

(a) \(y = \dfrac{10}{x^2}\) (1)
(b) \(y = x - 3 + 3x^2 - x^3\) (1)
(c) \(y = -\dfrac{3}{x}\) (1)
