How to Construct a Polynomial Function Given Its Graph

Описание: When I was at school I wanted to know how to construct my own formulae. Eventually, I learned a few clever techniques, and this is one of them.

If you know the roots and y-intercept of a polynomial (or can find them from a graph), it is quite "easy" to generate the polynomial function that generates that graph.

This is a good way for you to consolidate your understanding of how to sketch polynomials, because you have to use the same key insights in order to find their formulae!

When I have created the worksheet, I will create a link to it here.
