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)

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
