Use polynomial graph shape and end behavior to determine which of the following could be the x-coordinates at which the relative maximum and relative minimum occur in the given function. f(x) = 8x - 4x + 6 a. the relative maximum is at x - 1 and the elative minimum is at x = 0.33 b. the relative maximum is at x - 1 and the relative minimum is at 1-0.33. c. the relative maximum is at x = 0 and the relative minimum is at x-0.33. the relative maximum is at x - and the relative minimum is at x = -0.33. d. select the best answer from the choices provided co
