Question 402082: if f (x)=3x-4 and g(x)=x+2, find f+g
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!
To find f+g, just add them together, and combine like terms.

f+g=4x-2

If you need more help with functional notation, please see my own website. I have an entire curriculum posted on my website, all FREE. Look for the link near the top of my Homepage that says "Basic, Intermediate, and College Algebra: One Step at a Time," click on "College Algebra", and look in Chapter 2 for the topic called "The Algebra of Functions". There you will find lots of user-friendly explanation, examples, and exercises on I also have lots of problems that are solved in COLOR for you, and even videos on certain topics that may be of interest to you, videos from my own classrooms a few years ago before I retired. It's all FREE!!
