A student divided f(x) = 3x+ 8x2 +5x- 4 by x + 2 and found the remainder was r -6. Based on the remainder theorem, what can be concluded about f(x)? %3D The y-intercept of the graph of f(x) is -6. The function f(æ) = 3x + 8x2 + 5x – 4 has a zero at -6. The point (-2,-6) lies on the graph of f(x). The function f(x) 3x + 8x2 + 5x-4 has a zero at -2.
