PLEASEE HELPPPPP ITS TIMED!!!!!!

Which quadratic function has a leading coefficient of 2 and a constant term of –3?
A f(x) = 2x^3 – 3
B f(x) = –3x^2 – 3x + 2
C f(x) = –3x^3 + 2
D f(x) = 2x^2 + 3x – 3

Answer 1

Only 2 of these are quadratic functions: B and D, because their highest power is 2.
The leading coefficient is the coefficient of the x^2 term, which is -3 for B and 2 for D.
The constant is the number without a variable. For B it is 2 and for D it is -3.
The answer is letter D

Answer 2

Answer: D

A is not a quadratic equation, B's leading coefficient is 3 and the constant is 2, and C is also not a quadratic equation.
