Hi,(adsbygoogle = window.adsbygoogle || []).push({});

Please Can You Help Me To Understand How To Find The Vertex Of A Quadratic Equation (x,y Coordinates) Just By Looking At The Equation ?

Eg What Is The Vertex Of Y=3x^2+4x+7 ?

Also, How Do I Transform A Straight Line Graph Left Or Right On The x Axis Without Moving The Line Up/down Along The Y ?

Thanx

Roger
