14 Here are some graphs.

Nine sketch graphs labelled A to I: A exponential growth curve above the x-axis; B reciprocal-type curve with branches in the second and fourth quadrants; C sine-type wave through O rising; D cosine-type wave with maximum on the y-axis; E U-shaped parabola below the origin; F cubic curve through O rising from bottom left to top right; G n-shaped parabola with maximum at O; H reciprocal curve with branches in the first and third quadrants; I decreasing exponential curve above the x-axis

In the table below, match each equation with the letter of its graph.

EquationGraph
\(y = \sin x\)
\(y = x^3 + 4x\)
\(y = 2^x\)
\(y = \dfrac{4}{x}\)
