Answer 2

Answer:

option (2)

Step-by-step explanation:

f(X) = 2x3-9x2+X+12

if we put X = -1 , 4, 3/2 then,

f(-1) = 2*(-1)3 -9(-1)2 + (-1) + 12

= -2 - 9 - 1 + 12

= 0

f(4) = 2(4)3 -9(4)2 + 4 + 12

= 128 - 144 + 4 +12

= 0

f(3/2) = 2(3/2)3 -9(3/2)2 + 3/2 + 12

= 27/4 - 81/4 + 3/2 +12

= 27 - 81 +6 + 48 /4

= 0
