Question

f(x) = (x) is ... function on
(-0,0)
a. increasing
b. decreasing
c.not increasing not decreasing​

Answer 1

Answer:

I think increasing......

Answer 2

Answer:

In either case, it can be shown that x 3 is increasing even when x=0. ... f' > 0 implies f increasing only on an interval. For instance f: ℝ\{0} → ℝ defined by f(x) = −1/x has a strictly positive derivative, and it's not increasing since f(−1) = 1 and f(1) = −1.

but the answer is increasing
