Too bad I've forgot how to do this though. I'll paste the problem:
f(x) = 16000 + 50x + 0.2x^2
What happens if x = x+1 (increase by one)?
I believe it's something like this:
50(x + 1) + 0.2(x+1)^2 ->
50x + 50 + 0.2(x^2 + 2x1 + 1^2) ->
50x + 50 + 0.2x^2 + 0.2x + 0.2 ->
(I'm not sure about the next step because of my bad algebra skills): Possibly ->
50.2x + 50.2 + 0.2x^2
or
50x + 50.2 + 0.4x^2
Could anybody please help?
Thanks. :)
