Final answer:
The question inquires about a polynomial function which appears to be a quadratic expression, likely 'x² + x - 1'.
Polynomial functions are algebraic expressions that include operations like addition, multiplication, and non-negative integer exponents.
Step-by-step explanation:
The four most common types of polynomials that are used in precalculus and algebra are zero polynomial function, linear polynomial function, quadratic polynomial function, and cubic polynomial function.
In the given question seems to be asking for clarification on whether the expression 'Radial x the power of 2 sum x and minus 1 in the power of 2 brake' is a polynomial function.
Polynomial functions are expressions composed of variables and coefficients, involving only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
Examples of polynomials:
- 2a + 5b is a polynomial of two terms in two variables a and b.
- 3xy + 5x + 1 is a polynomial of three terms in two variables x and y.
- 3y4 + 2y3 + 7y2 – 9y + 3/5 is a polynomial of five terms in two variables x and y.
- m + 5mn – 7m2n + nm2 + 9 is a polynomial of four terms in two variables m and n.
