Well, variables are stuff like x and y because they can represent a number. They are variable in an equation. so if you have (3x^3)+(5X^2)+Y+9 then your variables are x X and Y (im assuming the capital X is there and not a typo) if that was a typo and meant to be lowercase, then its just a 2 variable with the x and y
Think, if something waves up and down at a certain rate, then its slope also will be changing with it along this wave at the same rate. If a function is periodic, with period c, then so is its derivative. I hope that this is the answer that you were looking for and it has helped you.
Answer:
X=2
Y=1/4*2
Y=1/2
Y=.5
Step-by-step explanation:
PROOF
2*2+2*.5=5
4+1=5
5=5
