Hey, I'm just starting out with calculus and am giving the Spivak book a try per threads on here. In the introduction to functions chapter spivak defines a function f(x) =x^2. for all x such that -17 ≤ x ≤ π/3
Then says you should be able to check the following assertion about the function defined above:
f(x+1) = f(x) + 2x + 1 if -17 ≤ x ≤ (π/3) - 1
I don't understand why there a negative one is now needed at the end of the domain
