Question

Which equation represents a quadratic function with a leading coefficient of 2 and a constant term of –3? f(x) = 2x3 – 3 f(x) = –3x2 – 3x + 2 f(x) = –3x3 + 2 f(x) = 2x2 + 3x – 3

Answer 1

Quadratic function: A quadratic function has a single variable x (say) with leading coefficient being non-zero, associated with the term x².

Solution:

• Option A. f(x) = 2x³ - 3
• This is not a quadratic function because it contains the term x³.

• Option B. f(x) = - 3x² - 3x + 2
• It is a quadratic function for sure, but its leading coefficient is (- 3), not 2.

• Option C. f(x) = - 3x³ + 2
• This is not a quadratic function because it contains the term x³.

• Option D. f(x) = 2x² + 3x - 3
• It is a quadratic function for sure, with leading coefficient 2 and constant term (- 3).

Option D is correct.
