Determine the indicated end behavior of each function. Enter a numerical value, -co, or co . (a) Right end behavior: (i) y = - x (x+ 3) (x+ 12)9. As X - 00, y = (ii) y = ax + bx - cx# where a, b, and c are positive constants. As X -> 00, y- (b) Left end behavior: (i) y = 16 + x (16 - X) 3 As X -> -00, y - (ii) y = x - 12 x 4 As X -> -00, y
