Question

Calc concave up down question

Answer 1

\[f'(x)=\frac{ 2x }{ e ^{x ^{2}} }\] where is the concave up?

Answer 2

Do you remember the concavity test?

Answer 3

nope

Answer 4

Find the second derivative, f''(x). If f''(x) > 0, then concave up. If f''(x) < 0, then concave down.

Answer 5

ah
ty

Answer 6

np :)

Answer 7

be careful though, because you already have the first derivative f'(x). :)

Answer 8

\[\int\limits\]

i just need to copy this symbol :/
