We know that,
Linear polynomial: A polynomial of degree one is called a linear polynomial.
Quadratic polynomial: A polynomial of degree two is called a quadratic polynomial.
Cubic polynomial: A polynomial of degree three is called a cubic polynomial.
The highest power of 7x3 is 3
the degree is 3
Hence, 7x3 is a cubic polynomial.
