Function notation and finding the value of a function from an input.
- Functions HW - Homework with answers based on functions.
- Functions? - Determine whether a variety of graphs are functions or not.
- Vertical Line Test - Check to see if your graph is a function by using the vertical line test.
- What is a function? - Learn about what functions are and how they work.
- Function Machine Questions - Given an input to a function, determine what the output will be.
- Function Machine - Determine from your own inputs and outputs what the function is.
- Function Notation and Terminology - A summary of what a function is and the terminology for functions.
- What is function notation?
- Given that f(x) = x^3 - 3, how do you find f(-2)?
- What is h(1.6) if h(x) = 0.3x^2 - 3x - 2.7?
- Given f(x) = x^3 - 3, how do you find f(2t)?
- How do you plug an expression with numbers and letters into a function?
This lesson explains function notation and finding values of a function given an input for the function. This concept of using f(x) instead of y is sometimes a confusing concept to students, but this concept is explained very well in this lesson. Several examples are shown and explained.
