A mathematical function is a formula that takes an ... How to Find the Y-Intercept of a Line of a Graph in Excel on a Mac How to Find the Y-Intercept of a Line of a Graph in Excel on a Mac.

Microsoft Excel has several powerful formula functions, including both slope and y-intercept ... straight lines and markers" option to create a graph of the linear equation.

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 ...

Find the equation of the line of symmetry and the coordinates of the turning point of the graph of \(y = x^2 – 6x + 4\) The coefficient of \(x^2\) is positive, so the graph will be a positive U ...

From the graph, we can also see that the y-intercept is 6, therefore we can say that the equation of the straight line is \(y = mx + 6\). Now we need to find the gradient.

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...
