Draw graphs of the sine and modulus functions and explain the humps.

Knowing two of the equations find the equations of the 12 graphs of cubic functions making this pattern.

Here is a pattern composed of the graphs of 14 parabolas. Can you find their equations?

The illustration shows the graphs of fifteen functions. Two of them have equations y=x^2 and y=-(x-4)^2. Find the equations of all the other graphs.

Observe symmetries and engage the power of substitution to solve complicated equations.

Use functions to create minimalist versions of works of art.

What functions can you make using the function machines RECIPROCAL and PRODUCT and the operator machines DIFF and INT?

Here is a pattern for you to experiment with using graph drawing software. Find the equations of the graphs in 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.

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.

Prove that the graph of f(x) = x^3 - 6x^2 +9x +1 has rotational symmetry. Do graphs of all cubics have rotational symmetry?
