Answer
It is a polynomial $f(x) =4x^4+5x^2$ of degree: $4$
Leading term: $4x^4$
Constant: $0$
Work Step by Step
A polynomial can be defined as a function containing only terms where $x$ is raised to a positive, integer power or constants. We can see from the given function that it is a polynomial. The degree is equal to the power of the term with the highest power, so the degree is $4$. Also, the constant value is $0$.
The term with the highest degree is always known as the leading term; that is, $4x^4$.
