Which set of ordered pairs represents a function? \{(-3, 7), (7, -3), (-7, 6), (-7, -1)\}{(−3,7),(7,−3),(−7,6),(−7,−1)} \{(7, -3), (-3, -9), (-3, -8), (8, 1)\}{(7,−3),(−3,−9),(−3,−8),(8,1)} \{(8, -9), (4, -8), (-4, 0), (-2, -8)\}{(8,−9),(4,−8),(−4,0),(−2,−8)} \{(-2, 8), (-3, -3), (1, -4), (1, 9)\}{(−2,8),(−3,−3),(1,−4),(1,9)}

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
