1. Find the absolute extrema of the function
f(x) = 3×4 – 4×3 on the interval (-1,2].
W4
+ 2w
2. Verify directly that
F(x) = xex, G(u) = u? ln u + u?, and H(w) = 7
are the antiderivatives of
f(x) = x(2 + 3×3)ex), g(u) = u(3 + 2 In u), and h(w)
=
2w3+1
Vw4+2w
respectively
3. Find the following indefinite integrals by the Basic Rules in Integration
du and S(2×2 + 1)(3x – 4)dx
su*-3u²+u
2u
4. Use the Substitution Method, to find the indefinite integrals
5 2x(3×2 – 1)5dx and Swa, dw
5. Evaluate the definite integrals
