Math Problem Statement
Determine whether the following function is a polynomial function. If the function is a polynomial function, state its degree. If it is not, tell why not. Write the polynomial in standard form. Then identify the leading term and the constant term. g(x)equalsx Superscript five halves Baseline minus x squared plus 8
Solution
Let's analyze the given function:
Step 1: Is it a polynomial function?
A polynomial function is one where all exponents of the variable are non-negative integers. Let's examine each term:
- The term has an exponent that is not an integer (it's a fraction), which violates the definition of a polynomial function.
- The term is fine because 2 is a non-negative integer.
- The constant term is also acceptable.
However, since involves a fractional exponent, this function is not a polynomial function.
Step 2: Why it is not a polynomial?
The function is not a polynomial because the first term, , has a fractional exponent. Polynomial functions must have exponents that are whole numbers (integers).
Conclusion:
The function is not a polynomial due to the fractional exponent in . Therefore, no degree, leading term, or constant term can be identified under the context of polynomial functions.
