A quadratic function exam question is shown below:
The diagram below shows the height of the path of a small rocket which is fired into the air. The height, h metres, of the rocket after t seconds is given by h(t) = 16t – t².
(a) After how many seconds will the rocket be at a height of 60m?
(b) Will the rocket reach a height of 70m? Justify your answer

A quadratic function is of the form f(x) = ax2 + bx + c where a, b & c are numbers which are not equal to zero.
It is like a machine. You put in one number, and it transforms it into another number using a preset rule.
The graph of a quadratic function is a curve called a parabola which may open upward or downward and vary in width or steepness, but they all have the same basic U shape.
We cover everything you need to know about Quadratic Functions in the Study Guides.
