1. FUNCTIONS notation

2. Function Notation f(x) = 5x – 9
A function is often represented using function notation as shown below….
f(x) = 5x – 9
This is read, “the value of the function (f) at x is 5x – 9”
-when you plug in a value for x, you will get the function value
Example…if x = 2, the value of the function is 1 because 5(2) – 9 = 10 – 9 = 1

3. Find the values of the function given the domain values…..
f(x) = 2x + 3
a. f(-2)
b. f(-1)
c. f(0)
d. f(1)
e. f(2)

4. Find the values of the function given the domain values…..
a. h(-2) b. h(-1) c. h(0) d. h(1) e. h(2)

5. Find f(2), f(-3) and f(-6) in the following function.
