Question

Classify the following as a constant, linear, quadratic and cubic polynomials:

`sqrt(2)x - 1`

Answer 1

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.

Power of x = 1.

The highest power of the variable x in the given expression = 1

Hence, the degree of the polynomial = 1

Since it is a polynomial of degree 1, it is a linear polynomial.
