In this video series we will investigate the basics of what you will need to know to be successful in Pre-Calculus. We will start with learning about linear equations and writing the equation of a ...

👉 Learn how to graph the square root function. Like other functions, to graph the square root function, we first graph the parent function (i.e., the graph of f(x) = square root of x) and then we ...

If \(f(x) = x^2\), then \(af(x) = a(x^2)\). This tells us that we need to multiply each of the \(y\) coordinates on the graph by \(a\) in order to stretch the original graph. Looking at some ...

A function is a way of describing what happens to an input variable, in order to get the output result. \(\text{Input} \rightarrow \text{FUNCTION} \rightarrow \text{Output}\) If we think of a simple ...
