What is a polynomial function?

Back

A polynomial function is a mathematical expression that involves a sum of powers in one or more variables multiplied by coefficients. The general form is f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n, a_(n-1), ..., a_0 are constants and n is a non-negative integer.

What does the degree of a polynomial indicate?

Back

The degree of a polynomial is the highest power of the variable in the polynomial. It indicates the polynomial's behavior and the number of roots it can have.

What is the leading coefficient of a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree in a polynomial. It influences the end behavior of the polynomial function.

What are the transformations of the function f(x) = (x - 3)^2 + 5?

Back

The function is transformed right 3 units and up 5 units from the parent function f(x) = x^2.

How do you find the perimeter of a polygon using polynomials?

Back

To find the perimeter of a polygon, sum the lengths of all sides, which can be expressed as a polynomial if the lengths are given in terms of a variable.

What is the expression for the total cost of a ticket, seat upgrade, and premium movies if given as (20x + 4), (4x), and (2x + 1)?

Back

The total cost is represented by the expression (20x + 4) + (4x) + (2x + 1) = 26x + 5.

How do you calculate the area of a sidewalk given the areas of two rectangles?

Back

To find the area of the sidewalk, subtract the area of the smaller rectangle from the area of the larger rectangle. If the areas are given as polynomials, perform polynomial subtraction.

What is the difference between two polynomial profit models?

Back

To find the difference between two profit models, subtract one polynomial from the other. For example, if Darnell's profit is 2c^2 - 7c - 200 and Stephanie's is c^2 + 8c - 100, the difference is (2c^2 - 7c - 200) - (c^2 + 8c - 100) = c^2 - 15c - 100.

What is a quadratic polynomial?

Back

A quadratic polynomial is a polynomial of degree 2, typically in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.

What is the standard form of a polynomial?

Back

The standard form of a polynomial is written in descending order of the degree of its terms, starting with the term of the highest degree.
