The speed of light is about 299,800 kilometers per second.
how many kilometers can light travel in one day? write the answer in scientific notation

B and C

Step-by-step explanation:

In a function, the x-coordinate cannot repeat. If it does, then it must equal the same thing as the other x-coordinate.

We already have 6, 8, and 9 and they equal 9, 3, and 10 respectively. The last coordinate is (x,4). In other words, x cannot be equal to 6, 8, or 9 since if they were, the table would not represent a function.

Therefore, of the given choices, B and C are correct since x cannot be equal to them in order to allow the table to remain a function.
