FUNCTIONS notation

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

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)

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)

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