Which equation represents a quadratic function with a leading coefficient of 2 and a constant term of –3?

A quadratic function has a highest power of x equal to 2. Its leading coefficient is the number multiplying x², and its constant term is the standalone number. In f(x) = 2x² + 3x – 3, the leading coefficient is 2 and the constant term is –3, so choice D is correct.
