Yes, it is a function
Step-by-step explanation:
Every possible input x value is paired with a unique output y value.

Volume of cylinder
v = πr²
v = 22/7 x 21²
v = 1385.441 cm³
Answer:
The answer is C. 16x² - 56xy + 49y²
Step-by-step explanation:
A perfect square trinomial is the result of a squared binomial, the perfect square trinomial would be a² + 2ab + b², as that is what you get when you expand the brackets.
Non linear because nothing cubed or squared can be linear.
