Find the Domain 2x^2-11x+15

Problem

2*x2−11*x+15

Solution

1. Identify the type of function provided. The expression 2*x2−11*x+15 is a polynomial function of degree 2, also known as a quadratic function.

2. Determine if there are any restrictions on the variable x Polynomials do not contain any operations that restrict the input, such as division by zero (fractions with variables in the denominator) or taking the square root of a negative number.

3. Conclude that the function is defined for all real numbers because any real value substituted for x will result in a real number.

Final Answer

Domain: *(−∞,∞)
