The statements that are true are A, B, and D
That's not a function.
Since a vertical line hits the graph more than once, if fails the test. (See graph below)
If it is a function, any vertical line you draw can only hit the graph once.
<span>It might be helpful to remember that the definitions of R2 and R3 are not geometric at all. R2 is the set of all ordered pairs of real numbers, whereas R3 is the set of all ordered triples of real numbers. W is a subspace fo R3, and so it still consists of elements which are triples, not pairs.
The fact that R2 and W can be visualized with the same geometric picture, namely the xy plane, is one way to see in a concrete way the isomorphism which the second poster refered to.</span>
Answer:
2 to 6
Step-by-step explanation:
If 6 teachers prefer expo markers then 6-8=2 then there are two teachers that don't prefer markers and 6 that do so the equals 2:6
