Textbook Question
Fill in the blank(s) to correctly complete each sentence. A polynomial function with leading term 3x5 has degree ____.
Verified step by step guidance1
Recall that the degree of a polynomial function is the highest power of the variable in the polynomial.
Identify the leading term of the polynomial, which is the term with the highest exponent on the variable.
In this problem, the leading term is given as \$3x^{5}\(, where the exponent on \)x$ is 5.
Therefore, the degree of the polynomial function is the exponent of the leading term, which is 5.
Fill in the blank with the number 5 to complete the sentence: "A polynomial function with leading term \$3x^{5}$ has degree 5."

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Polynomial Function
A polynomial function is an expression consisting of variables and coefficients combined using only addition, subtraction, multiplication, and non-negative integer exponents. For example, 3x^5 + 2x^3 - 7 is a polynomial function.
