    The way a function works is it is defined with a variable (usually shown as 'x', but not always), that can take on different values. To find the value of the function for a given value of 'x' you simply replace the 'x' in the equation with the value. For example: given

    f(x) = 2 - 3x

    then for x = 1 you would get:

    f(1) = 2 - 3(1) = -1.

    Use this same process to find f(-8), f(0), and f(2).
