👉 Learn how to find the value that makes a function continuous. A function is said to be continuous if two conditions are met. They are: the limit of the function exists and the value of the function ...

👉 Learn how to graph piecewise functions. A piecewise function is a function that has more than one sub-functions for different sub-intervals (sub-domains) of the function's domain. To graph a ...

To find solutions from graphs, look for the point where the two graphs cross one another. This is the solution point. For example, the solution for the graphs \(y = x + 1\) and \(x + y = 3\) is the ...

Curved graphs can be used to solve equations. The points at which the curve crosses a particular line on the graph are the solutions to the equation. If we want to solve the equation ...
