the parabola represents the graph of the quadratic function f (x) = 2x^2 + 6x + 4.5. which of the following describes the domain of this function?

Answer 1

The function \( f(x) = 2x^2 + 6x + 4.5 \) is a quadratic function. Quadratic functions are defined for all real numbers, which means their domain is all real numbers.

Therefore, the domain of the function \( f(x) \) can be described as:

\[ \text{Domain: } (-\infty, \infty) \]
