Compare Dy And $\Delta y$ For $y = 3 x ^ { 2 } - 3$

Compare dy and $\Delta y$ for $y = 3 x ^ { 2 } - 3$ at x = 2 with $\Delta x =$ dx = -0.07. Give your answers to four decimal places.

A) $d y = - 0.8500 , \quad \Delta y = - 0.8255$
B) $d y = - 0.8400 ; \quad \Delta y = - 0.8253$
C) $d y = - 0.8700 , \quad \Delta y = - 0.8254$
D) $d y = - 0.8200 , \quad \Delta y = - 0.8256$
E) $d y = - 0.8200 , \quad \Delta y = - 0.8254$
