Since \(k = - 1\), then this parabola will have a maximum turning point at (-4, -5) and hence the equation of the axis of symmetry is \(x = - 4\).

By calculating a function at a large number of set intervals, it is possible to create a scatter plot of a function. In business this has many uses. For example ... a Line of a Graph in Excel ...

MIN(range); =MAX(range) where range equals the list of numbers you’re calculating. Common uses of this function are; for example, find the highest/lowest grade in a classroom; the highest/lowest ...

the vertex is a maximum turning point We can identify these properties from a quadratics graph or equation.
