What is Standard Form in polynomials?

Back

Standard Form of a polynomial is when the terms are arranged in descending order of their degree.

Front

Is the expression 6w^2 - 9w^3 in Standard Form?

Back

No, it is not in Standard Form because the term with the highest degree (9w^3) should be first.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function f(x) at a point x=a, substitute a into the function: f(a).

What is a polynomial?

Back

A polynomial is an expression consisting of variables raised to non-negative integer powers and coefficients.

Front

Front

What is the leading coefficient of a polynomial?

Back

The leading coefficient is the coefficient of the term with the highest degree in the polynomial.

Front

What is the leading coefficient in the polynomial 3x^2 - 2x + 5?

Back

The leading coefficient is 3.

Front

What does the degree of a polynomial indicate?

Back

The degree of a polynomial indicates the highest power of the variable in the expression.
