2000 AB 4
c) A(t) = 30 +∫t0 8 - sqrt(x+1) dx
A(t) = 30 + 8t - ∫t0 sqrt(x+1) dx
d) A’(t) = 8 - sqrt (x-1); A(t) = 0 when t = 63
A’(t) is positive for (0, 63) but negative for (63, 120); therefore, there is an absolute maximum at t=63.

d) establish that since g(1) = 2), g-1 (2) = 1
g-1’(x) = 1/g’(g-1(x))

b) increasing on [-6, -2] u [2,5] since f’(x) > 0 for [-6, -2) u (2, 5)
d) Find limit on left and right, but then use slope formula with generic point as first and f’(3) as second to prove at end.

a) Make sure you state equations equal each other, and then B
d) d/dt (A(x)) = DA/dx (dx/dt)
D/dt (A(x))| x=-0.5 = A’(-.0.5)(7) = -9.272


2022 AB 5
d) Coefficient of cos is -1/pi
