An advantage of this notation is that it can easily be generalized by adding more terms. We could for example write equations such as y = a + bx + cx 2 + dx 3 Notice that the graph of the quadratic ...

Using the quadratic formula is another method of solving quadratic equations that will not factorise. You will need to learn this formula, as well as understanding how to use it. Key fact The ...

As a graph cuts the axis when the y coordinate is zero, then we substitute \(y = 0\) into the quadratic equation and use algebra to solve. We need to factorise the trinomial. When factorised this ...

Linear, constant, absolute value or modulus, logarithmic, exponential, reciprocal, goniometric or trigonometric, quadratic or polynomial, and cubing, cube, or cubic function. Mathematics, second ...
