If f(x) = 3x2 - 2x+4 and g(x) = 5x + 6x - 8, find (f - g)(x). O A. (f- g)(x) = 2x2 + 4x - 4
O B. (f- g)(x) = 8x2 + 4x - 4
O c. (f- g)(x) = -2x2 + 8x - 12
O D. (f- g)(x) = -2x2 - 8x + 12

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
