(i) 1+x
The highest power of 1 + x is 1
the degree is 1
Hence, 1 + x is a linear polynomial.
(ii) 3t
The highest power of 3t is 1
the degree is 1
Hence, 3t is a linear polynomial.
(iii) r2
The highest power of r2 is 2
the degree is 2
Hence, r2 is a quadratic polynomial.
(iv) 7x3
The highest power of 7x3 is 3
the degree is 3
Hence, 7x3 is a cubic polynomial.
