Question

If f(x)=2-x then f(x+h)=

Answer 1

Hello, thank you for taking the time to post your question!

If you’re starting with

f(x) = 2 – x, that means that

f(x + h) = 2 – (x + h) = 2 – x – h

essentially the idea is that you just replace x with (x + h) and then simplify as much as possible

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

f(x + h) = 2 - x - h

Answer 3

You just need to plug in "x + h" into f(x) = 2 - x wherever you see an "x" so:

f(x + h) = 2 - (x + h)

f(x + h) = 2 - x - h
