Question

The inverse property of addition states that, for every
integer 'x',
(a) X-0 = x (b) x + x = 0
(C) x + (-x) = 0 (d) x+0=x

choose the correct one ​

Answer 1

Answer:

δ > 0 such that f(x) ≤ f(x0) whenever x ∈ I ∩ (x0 − δ, x0 + δ). ... b) and f (c)=0. Proof: If f is constant on [a, b] then f (c) = 0 for all c ∈ [a, b].
