If f(x)= \int\limits^x_0 cos(t^2)dt for -2.5≤x≤2.5, on which interval is f increasing?

C

Step-by-step explanation:

It will be increasing when

cos(x²) > 0

cos is positive:

[0, pi/2]

0 < x² < pi/2

-sqrt(pi/2) < x < sqrt(pi/2)

people grow faster than other people.

step-by-step explanation:

should you really be posting this isn't math boi.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
