the assumption being that "x" is a plain variable whilst "y" is a function, that matters because the chain rule would be needed for a function, not so for a plain variable.
now, we know that y(5) = -23, which is another way of saying that when x = 5, y = -23, but we already knew that, we can get that by simply plugging it into the equation hmmm y'(5), well
The x=y
Is this the the test of the question?
Answer:
Ok time to get math on
So this would be D
A non-filled in dot means < or > (depending where arrow is pointing)
A filled in dot means ≤ or ≥ (depending where arrow is pointing)
if an arrow points right, then it would be greater than, if arrow points left.. Then its less than
So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D
A is greater than which is not the answer
B is only equal to which is way off
C is less than but it is equal which is wrong
D is the only right answer
Hope this helps! :)
<span>There are 4 main transformations: Rotation, Translation, Dilation and Reflection. Reflection is a transformation: flipping an object about a line. Reflection is distance-preserving transformation. The image has the same size as the original image ( in this case: ABC = A`B`C` ).The central line is called mirror line and here it is line BC. Answer: B. Reflection over segment BC.</span>
