## rebecca1233 3 years ago 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).

well for this, the possibilities are endless lol

4. rebecca1233

so ? can i use that ?

5. AriPotta

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

6. soty2013

simply put the value of given x in given f(x)

8. rebecca1233

so i just put any number so like f(2) = 3k+3?

9. soty2013

yes

10. rebecca1233

do i need to do anything else or just that ?

11. AriPotta

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

12. AriPotta

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

13. rebecca1233

ok so for the one i chose that is the answer ?

14. AriPotta

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