If you're talking about evaluating functions, then it works the exact same way as evaluating algebraic expressions. Replace all instances of the variable with its substituted value, and …

Functions come to life when we look at their graphs. In this unit, we’ll explore how features like symmetry, discontinuities, and intervals reveal deeper insights into function behavior.

Not all functions have inverses. Those who do are called "invertible." Learn how we can tell whether a function is invertible or not.

Functions Make your code more reusable by grouping it into functions. Use parameters and return values to pass information in and out of your functions.

While Boolean Algebra is a formal system leading into Discrete Math, the entry point, the topic is so much richer: combinatorics, graph theory, generating functions.

This is going to be true for all functions, so lets start with a linear equation y = x + 3. the y intercept is 3 (set x=0) and the x intercept is -3 (set y = 0).
