Question
Classify the following as a constant, linear, quadratic and cubic polynomials:
3
Solution
Constant polynomials: The polynomial of the degree zero.
Linear polynomials: The polynomial of degree one.
Quadratic polynomials: The polynomial of degree two.
Cubic polynomials: The polynomial of degree three.
There is no variable in the given expression.
Let us assume that x is the variable in the given expression.
3 can be written as 3x0.
i.e., 3 = x0
Power of x = 0.
The highest power of the variable x in the given expression = 0
Hence, the degree of the polynomial = 0
Since it is a polynomial of the degree 0, it is a constant polynomial.
