If f(x) = 3x2 + 2x – 7 represents the attitude score f(x) for a person x years old, find and interpret f(30?



Answers:
so f(30) means that you are trying to figure out the attitude score for a person 30 years old. I've never heard of an attitude test. But there is such a thing as an APTITUDE score.

so. x = 30...

f(30) = 3(30)^2 + 2(30) - 7 = 3(900) + 60 - 7 = 2700 + 60 -7 = 2753

So that's how you do this problem.

NOW.. take what you learned here, and I hope that with that newfound knowledge, you'll be able to solve similar problem on you own without any help from others. I KNOW that you can do it when you put your mind to the task. :o) Try it! You'll be amazed at what you can do!
Just put 30 in wherever there is an X.

earth and bhav... this is homework HELP, not "do my homework"
i think this question is nuts...who would do math in there spare time?
f(x) = 3x2 + 2x - 7
f(30) = 3 (30) (30) + 2 (30) - 7
= 3 (900) + (60) - 7
= 2700 + 53
= 2647
