Question

In the function
f(x) = x^2

how does a decrease of 1 in the independent variable x affect
f(x)?

Answer 1

f(x-1)=(x-1)^2
i think thats what you are asking

Answer 2

f(x) will have a change of x^2
f(x) will have a change of x^2 - 2x + 1
f(x) will have a change of 2x + 1
f(x) will have a change of 1 - 2x

Answer 3

D

Answer 4

f(x-1)-f(x) shud give you the ans

Answer 5

I know you have good intentions, Sarkar, but when you've already virtually provided the answer, you need to egg the asker on to answer it him/herself.

Answer 6

Thank you

Answer 8

@kayser Wanting people to learn rather than cheat is being a bad influence? How times have changed.

Answer 9

Stuff happens...

Answer 10

I feel that getting to know how the sum is done shud be the real motive of the student ,getting the answer is just an indication that the right formula has been used.

Answer 11

Getting the answer can be done via WolframAlpha. It's honestly a waste of time to get it here--unless the student really DOESN'T understand the subject material, and thus can't get the answer from WolframAlpha, but is still trying to cheat.

Answer 12

I do agree @badreferences
