The graph of which function is decreasing over the interval (4, )?
f(x) = (x + 4)2 + 4
f(x) = -(x + 4)2 + 4
f(x) = (x - 4)2 - 4
f(x) = -(x - 4)2 - 4

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
