F(x) = 8x
y = 8x
x = 8y
x/8 = y
y = x/8
f^-1(x) = x/8
We can solve this using Lopital theorem.
lim x₋>0 (x+sinx)/6x = lim x->0 (x+sinx)'/ (6x)' = lim x->0 (1+cosx)/6 = (1+1)/6 = 2/6=1/3
lim x->0 (x cosx - sin2x)/x = lim x->0 (x cosx - sin2x)' / x' =
lim x->0( cosx -x sinx - 2 cos2x) / 1 = 1 - 0 -2 = -1
Good luck!!!
The answer would be 15 because the problem states that it takes 8 hours to build 5 birdhouses and they want to know how many she can build in 24 hours if you multiply 8 and 5 with the number 3 you would get 24 hours and 15 birdhouses.
