Identify constant, linear, quadratic and cubic polynomials from the following polynomials:
$$g(x) = 2x^{3} - 7x + 4$$.
$$g(x)=2x^3-7x+4$$
Here, we can see highest degree of variable $$x$$ is $$3$$.
We know that,
A cubic polynomial is a polynomial of degree $$3.$$
$$\therefore$$ $$g(x)=2x^3-7x+4$$ is a cubic polynomial.
