Consider the equation below. (if an answer does not exist, enter dne.) f(x) = e9x + e−x (a) find the interval on which f is increasing. (enter your answer using interval notation.)

We have been given that

On differentiating we get

For the function to be increasing, the first derivative must be positive

f'(x)>0

Thus, the required interval is given by

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
