CIE A Level Maths: Pure 1复习笔记1.1.2 Quadratic Graphs

What are quadratic graphs?

Using quadratic graphs

You need to be able to:

• sketch a quadratic graph given an equation or information about the graph
• determine, from the equation, the axes intercepts
• factorise, if possible, to find the roots of the quadratic function
• find the coordinates of the turning point (maximum or minimum)

You may have to rearrange the equation before you can find some of these things
