Learn how to find the inverse of a function and how to graph it in this video. The inverse function swaps the x and y values of the original function, and the graph of this inverse function is a …

Let's explore different ways to find and visualize slopes and intercepts, and how these concepts can help us solve real-world problems. **Unit guides are here!**

GIven a graph of an exponential curve, we can write an exponential function in the form y=ab^x by identifying the common ratio (b) and y-intercept (a) in the graph.

Given the graph of a function, determine its domain or range.

Review the basic features of sinusoidal functions: midline, amplitude, and period.

Knowing the sign of a polynomial function between two zeros can help us fill in some of the gaps. In this article, we'll learn how to determine the intervals over which a polynomial is positive or …

If you can draw a vertical line anywhere on the graph and only pass thru one point on the graph at a time, then the graph is a function. The graph in the video fails the vertical line test because …

If you're struggling to figure it out, check out Desmos's Graphing Calculator. It shows you what the equation looks like on a graph, which can really help you understand what to look for!

Finding the domain and the range of a function that is given graphically. Created by Sal Khan.

Supposing you already know how to find increasing & decreasing intervals of a function, finding relative extremum points involves one more step: finding the points where the function …
