From the equation \(y = - {(x + 4)^2} - 5\), write down the co-ordinates and nature of the turning point and the equation of the axis of symmetry. Since \(k = - 1\), then this parabola will have a ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 ...

Perhaps the most familiar example ... of graphing algebraic equations in a field called analytical geometry. A variation of his methods is still used today. As shown below, the graph of a ...
