WebFirst, let's calculate f (8) using the function f (x): f (x) = 3x^3 - 2x + 7 f (8) = 3 (8)^3 - 2 (8) + 7 f (8) = 1535. Next, let's calculate h (8) using the function h (x): h (x) = x^2 - x + 1 h (8) = (8)^2 - 8 + 1 h (8) = 57. Now we can substitute these values into the equation f (8) = g (8)h (8) + r (8) and solve for g (8) and r (8). Web试题来源：2016-2024学年高三数学配套习题：第三章数系的扩充与复数的引入习题课 Word版含解析
