In this part you do not have to sketch the graph and you may even be given the sketch of the graph to start with. For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following ...

The tangent can be determined with a collection of mathematical formulas but is most commonly determined by dividing the sine function by the cosine function. Microsoft Excel simplifies the ...

When working with a large data set, you would be more productive if you knew how to quickly find what you need. Luckily, ...

The graph of the quadratic function \(y = ax^2 + bx + c\) is a smooth ... Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the equation to 1 decimal place.
