Save guides, add subjects and pick up where you left off with your BBC account. For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of the ...

A quadratic ... We use substitution to calculate the values. We replace the value of x for different numbers and record the resulting y value. These coordinates can then be plotted on a graph.

You can also plot graphs for trigonometric equations (equations that use sine, cosine, and tan, etc.), establish graphs for linear and quadratic ... For example, in the equation y=mx+c, you ...
