Part a.) Write your own function in function notation. For example: f(x) = x + 1. Using your function, find f(2). Part b.) Explain in your own words how to find the value of f(2) when you are given a function f(x).

    @soty2013 she has to make her own function, that was an example. i don't think she can use the example :/

    if you use f(x) = 3x + 3, then you'd have to then solve for f(2)

    so f(2) = 3(2) + 3 f(2) = 6 + 3 f(2) = 9

    yea part a: f(x) = 3x + 3 part b: f(2) = 3(2) + 3 f(2) = 6 + 3 f(2) = 9
