The function f is given by f(x) = 1 + 3 cosx. What is the average rate of change of f over the interval [0, pi]?
A. -6/pi
B. -2/pi
C. 2/pi
D. 1

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

the height of the surface increases from the center out to the sides of the road

it is c!

49/6 is going to equal 8 1/6

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
