Mathew Chaney · Answer 1

Option D. The circumference

Step-by-step explanation:

A). Area 'y' of square with side 'x' will be represented by

y = (Side) ²

y = x²

Since the degree of this polynomial function is 2, It's a quadratic equation.

B). Area of the circle = πr²

y = π (x) ²

Since the degree of this polynomial function is 2, It's a quadratic equation.

C). Volume of a cube = (Side) ³

y = x³

Since the degree of this polynomial function is 3, It's not a linear function.

D). Circumference of the circle = 2πr

y = 2π (x)

Since the degree of this polynomial function is 1, it's a linear function.
