The illustration shows the graphs of fifteen functions. Two of them have equations
$y = x^2$
$y = - (x - 4)^2$
Can you find the equations of the other parabolas in the picture?
You may wish to use a graphical calculator or software such as Desmos to recreate the pattern for yourself.
Can you find the equations of these parabolas?
Prove that the graph of f(x) = x^3 - 6x^2 +9x +1 has rotational symmetry. Do graphs of all cubics have rotational symmetry?
In this 'mesh' of sine graphs, one of the graphs is the graph of the sine function. Find the equations of the other graphs to reproduce the pattern.
The illustration shows the graphs of twelve functions. Three of them have equations y=x^2, x=y^2 and x=-y^2+2. Find the equations of all the other graphs.
