Answer:
D,
Step-by-step explanation:
D would be the only one that doesn't represent a function because the y-value never changes while the x-value does.
-2
We know that a positive and a negative will end in a negative result. (+) (-) = (-)
The average rate of change of <em>f(x)</em> on -3 ≤ <em>x</em> ≤ 3 is given to be
(<em>f</em> (3) - <em>f</em> (-3)) / (3 - (-3)) = -2.5
If <em>f</em> (-3) = 14, then
(<em>f</em> (3) - 14) / (3 + 3) = -2.5
(<em>f</em> (3) - 14) / 6 = -2.5
<em>f</em> (3) - 14 = -15
<em>f</em> (3) = -1
