Answer:
A
Step-by-step explanation:
In a function, each x value must have a singular y value. This means that one x-value (the values on the left) may not have a line pointing to 2 different y-values (the values on the right). In the first relation, the x-value of 6 points to both 4 and 6. This means that the value repeats, and in a function x-values cannot repeat.
However, y-values can repeat. So, situations like that seen in D, where both the x-values of 2 and 4 equal the y-value of 6 are fine.
-50 to -51; 49 to 50; -48 to -49; 48 to 49; 50 to 51
I just add one
256.
The coefficient of just the y term would be 256 because the entire expanded equation looks like this:
y^4+16y^3+96y^2+256y+256
i think its
6x4-1 that should be the awnser
