Function Notation and Evaluation
The functions f(x), g(x) and h(x) are shown below. Click and slide the red diamond to change the value of x. As x changes the values of each of the functions is updated. Try sliding the diamond and observe how the function values change. After you are familiar with the operation of the lab answer the questions below (write them down for use on the quiz). 1. Find the value of the functions for x = 3. 2. Find g(3). 3. Find f(x)=9. 4. Find h(x) when g(x)=39. 5. Set x = -1 (negative 1) and record the value of the functions.
