Find Coefficients in y=-4x²-3x: Quadratic Expression Analysis

To solve this problem, we'll identify the parameters $a$, $b$, and $c$ in the quadratic function.

The quadratic equation provided is $y = -4x^2 - 3x$. To match this equation with the standard quadratic form $y = ax^2 + bx + c$, we must determine the values of $a$, $b$, and $c$.

• Step 1: Identify $a$. The coefficient of $x^2$ in the given equation is $-4$. Thus, $a = -4$.
• Step 2: Identify $b$. The coefficient of $x$ in the given equation is $-3$. Thus, $b = -3$.
• Step 3: Identify $c$. The constant term (the term not involving $x$) does not appear in the equation, which means $c = 0$.

Therefore, the values of the parameters are $a = -4$, $b = -3$, and $c = 0$. This matches with choice 3 in the provided options.

The correct answer is $a = -4, b = -3, c = 0$.
