Identify Variable Power: Identify the highest power of the variable in the polynomial.In the given polynomial 4d, the variable d is raised to the power of 1, since any variable without an explicit exponent has an implied exponent of 1.
Determine Polynomial Degree: Determine the degree of the polynomial.The degree of a polynomial is the highest power of the variable in the polynomial. Since the highest power of d in 4d is 1, the degree of the polynomial is 1.
