More practice with relations and functions.
- 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?
- If P(x) = 3x - 2 and Q(x) = x^2 + 1, what is Q(x) - P(x) and Q(x)*P(x)?
- If Q(x) = x^2 + 1, how do you find Q(2x - 7)?
- If P(x) = 3x - 2, what is P(x+h) and P(x + h) - P(x)?
- If Q(x) = x^2 + 1, what is Q(x + h) - Q(x)?
- If P(x) = 3x - 2 and Q(x) = x^2 + 1, what is P(-x) - Q(-x)?
- If P(x) = 3x - 2, what is P(a+h)?
This lesson builds upon the topics learned in the previous lesson in this series by finding the value of functions with a given input, but now there are multiple functions and they are added, subtracted, multiplied, and divided. Some expressions get a bit more complicated than previous problems. This technique is extremely important to understand for Calculus limits.
