Question

Could comebody identify this function? I'm rather clueless! It does not have an upper bound. https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-snc7/s720x720/376276_2299772751881_16457301_n.jpg

Answer 1

Looks almost like an inverted normal, but that doesn't keep increasing

Answer 2

Is it undefined or just really small when x<0?

Answer 3

Undefined.

Answer 4

I want to say that it is some sort of function:
\[a\sqrt[b]{x} + ...\]
where b is even

Answer 5

could it be piece wise?

Answer 6

I'm not entirely sure, but that wouldn't make much sense, would it, it'd be easy to find such function is it was piece wise.

Answer 7

let's think about the things we know:
f(1) = 1
f'(0) = 0
f'(x) >= 0

Answer 8

f"(1) = 0
f"(.5) > 0
f"(2) < 0

Answer 9

it looks like exponential... with change in path at point (1,1)
