A function is a rule for how two variables relate. For each value of x (the domain), there is only one value of y (the range). For example, if y=3x, whatever x is, y must be x multiplied by 3.
A function table shows the values for each pair of variables as the result of the particular function.
Complete the function table for the given function.
The first x-value in the table is 0. Evaluate f(x) = 3x for x = 0.
When x = 0, f(x) = 0. Complete the first row of the table.
Next, evaluate f(x) = 3x for x = 1.
= 1, f
) = 3. Complete the second row of the table.
Complete the rest of the table the same way.
