Quadratic Graphs

Definitions

quadratic

expression an expression of the form ax² + bx + c where a, b and c are numbers and x is the variable

(note that b and c can be zero, but a must be non-zero so that there is always an x² term)

e.g. x² + 5x + 6, 3x² – 3x + 17, 8x², 4x² – 25, 12x² – 30x

quadratic

equation an equation which can be written with a quadratic expression on one side and zero on the other

e.g. x² + 5x + 6 = 0, 3x² – 3x + 17 = 0, 4x² – 25 = 0

note that quadratic equations sometimes need rearranging to get zero on one side

e.g. x² = 3x – 2 can be rearranged to give x² – 3x + 2 = 0

quadratic

function a name normally given to a function of the form y = ax² + bx + c which is used to calculate y coordinates from given x coordinates so that these can be plotted on a graph

roots of a

quadratic the roots of a quadratic equation are the solutions to that equation

e.g. the roots of the equation x² + 5x + 6 = 0 are x = –2 and x = –3
