Question
Match all the equations.
Not just the graph
The graphs below show functions you should recognise without technological aid. (Note: the scales on each graph may differ.) For each equation below select the letter A, B,... corresponding to a matching graph above, or select "none" if there is no matching graph. y = x2 + 1 y = In x y = x3 y = -x x2 + y2 = 4 y = tan x y = -1/r x = 3 y = 1/x y = -2 y = ex y = -x2 + 1 x = y2 y = e-x y = 2/3x + 2 y = tan-1x y = sin x y = cos x y = x sin x y = (x - 2)2 - 3 (x + 2)2 + (y - 2)2 = 2
