Answer
We can give values for x and f(x) in a tabular format to define the function. Values of x are given with the corresponding values of f(x) below them
x -> 1, 0, 1, 2, 3, 4, 5,
f(x) -> 1, 3, 5, 7, 9, 11, 13
Work Step by Step
Consider the function f(x) = 2x + 3
Verbally
Multiply by 2 and add 3
Algebraically
f(x) = 2x + 3
Visually / Graphically
Shown is graph of f(x) = 2x + 3. x is on the horizontal axis and f(x) is on the vertical axis.
