Integration by Substitution. The rate of growth of Grass carp, one of the most common type of fish, was modelled by the equation 3x + 6 x² + 4x + 3 where t is measured in years and f(t) in kilograms per year. Consider the integral f(t) = 6² 3x + 6 x² + + 4x + 3 Ja After substitution into u, the new integral can be written A U du (a) The value of A is O 3x O 6 O 1.5 O 3 O 3x + 2 Ox Ox+2 O o dx (b) The upper limit of integration b is O 2 O 15 O-15 O 30 O 6 0-2
