Evaluate the function for the given values of a and b. Then use the intermediate value theorem to determine which of the statements below is true.a = -2 and b = -1f(x) = 5x4 + 6x3 - 8x - 10
A. f(-2 ) and f(-1) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between -2 and -1. B. f(-2 ) and f(-1) have opposite signs, therefore f has a real zero between -2 and -1. C. f(-2 ) and f(-1) have opposite signs, therefore f does not have a real zero between -2 and -1. D. f(-2 ) and f(-1) have the same sign, therefore f does not have a real zero between -2 and -1.
Graph the function f(x) over the given interval. Partition the interval into 4 subintervals of equal length. Then add to your sketch the rectangles associated with the Riemann sum
