Find the Domain y=8x^2-3x-9

Problem

y=8*x2−3*x−9

Solution

1. Identify the type of function. The given equation y=8*x2−3*x−9 is a polynomial function, specifically a quadratic function.

2. Determine any restrictions on the variable x For polynomial functions, there are no values of x that would result in division by zero or the square root of a negative number.

3. Conclude that the function is defined for all real numbers. In interval notation, this is represented as (−∞,∞)

Final Answer

Domain: *(−∞,∞)
