Standard form 

 

It is written as...

 

 

Can we graph this directly?

• No, we need information such as the x-intercept(s), or the vertex, in order to graph a parabola, however, in standard form we are not provided with this information.

 

So how do we graph it?

• Convert it into factored form if possible and graph.

• Change it into vertex form

• Use the quadratic formula
