Fractions containing powers - using indices rules

How to graph a quadratic equation that is in standard form using a table. I also show vertex form briefly as well.

How to find the quadratic equation from a number sequence - this is a better video than part 1. I explain some parts I didn't mention in part 1. So worth a watch, it will probably make more sense after watching it.

Sometimes they will want you to make a quadratic equation from a sequence of numbers or a pattern. You need to go through steps to work out what the sequence is to form the equation then substitute in values to check if you have the correct equation that solves it.

I attempt to explain how you can read a quadratic equation in root form and get the two roots (x - intercepts) and the y-intercept value from the equation to plot it, or use a table to get the actual values.

We can also get the equation for a quadratic from a graph.

Graphing quadratics using tables - and how to read and graph from the equation using basic knowledge of squared values. Sorry its a bit long.
