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 ...

Using the SLOPE function in Excel, you can find this value for a set of coordinates automatically. Launch Excel and open a spreadsheet containing coordinate data with the x and y values in ...

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.
