If [" f(t)dt - 3x7 + 12x, what are the possible values of a? Verify that your values of a are correct. Show all your work. For an indefinite integral, use the notation INT in place of the symbol. For example, J (x + 1) dx should be written as INT (x + 1) dc. For a definite integral, use the notation INT (a, b). For example, (x + 1) da should be written as INT (1, 2) (x + 1) dx. For a definite integral that has been integrated, use the notation EVAL (a, b). For example, should be written as 2 +0 EVAL (1, 2)
