Evaluate 14 - 2xy when x = -6 and y = 2.  answers -10, 28, 38, 52

So firstly, plug in -6 into the x variable and 2 into the y-variable:

Next, do the multiplication:

Lastly, do the addition, and your answer will be 38, or the third option.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
