Positive quadratic graphs (where \(a \textgreater\) 0) are U-shaped and have a minimum turning point. Negative quadratic graphs (where \(a \textless\) 0) are \(\cap\)-shaped and have a maximum ...

Quadratic graph lines are U- or Ո-shaped ... For \(y = -x²\), work out \(-x²\) (which is the negative value of \(x²\)). Draw and label the axes to include the minimum and maximum values ...
