<h3>
Answer: Choice C 
</h3>
The open circle means we do not include the endpoint, hence the use of a greater than symbol. If we were to include the endpoint, then we'd have greater than or equal to. We can rule out choice B due to this reasoning.
The ray pointing to the right indicates we are talking about x values larger than 5, so we can rule out choice A and conclude the answer is C.
Side note: The notation 
is saying "x is a real number"
I think it is 4 because it’s how many times it crosses the x axis
4y^3 - 2y^2
what is the largest number that divides evenly into 4y^3 and -2y^2?
it is 2
what is the highest degree of y that divides evenly into 4y^3 and -2y^2
it is y^2
the GCF is 2y^2
2y^2(2y - 1) <<<< answer
hope that helps, God bless!
Step-by-step explanation:
25, 400 and 144 are all square numbers and 24, 300 and 145 are not.
Therefore, he must like 1600
