I believe the answer is D.) 360
Answer: C
<u>Step-by-step explanation:</u>
(x - 3)² = 0
(x - 3)(x - 3) = 0
x(x - 3) -3(x - 3) = 0
x² - 3x -3x + 9 = 0
x² - 6x + 9 = 0
1. The coefficient of x is the constant of variation. It is 40.
2. -12 = -2*6 . . . . . you know this because you know your times tables
.. f(x) = -2x
