Find the Degree, Leading Term, and Leading Coefficient f(x)=9x^3-7x

$f (x) = 9 x^{3} - 7 x$

Step 1

The degree of a polynomial is the highest degree of its terms.

Identify the exponents on the variables in each term, and add them together to find the degree of each term.

$9 x^{3} \to 3$

$- 7 x \to 1$

The largest exponent is the degree of the polynomial.

$3$

Step 2

The leading term in a polynomial is the term with the highest degree.

$9 x^{3}$

Step 3

The leading coefficient of a polynomial is the coefficient of the leading term.

The leading term in a polynomial is the term with the highest degree.

$9 x^{3}$

The leading coefficient in a polynomial is the coefficient of the leading term.

$9$

Step 4

List the results.

Polynomial Degree: $3$

Leading Term: $9 x^{3}$

Leading Coefficient: $9$
