Constructing an Algebraic Expression: Parameters a = -1, b = 0, c = 0 Explained

Create an algebraic expression based on the following parameters:

$a=-1,b=0,c=0$

We begin by noting that the general form of a quadratic function is represented by the equation:

$y = ax^2 + bx + c$

Given the parameters $a = -1$, $b = 0$, and $c = 0$, we substitute these values into the equation:

$y = (-1)x^2 + (0)x + 0$

Simplifying the expression, we get:

$y = -x^2$

Thus, the algebraic expression representing the given parameters is $-x^2$.

The correct answer choice that corresponds to this expression is:

$-x^2$
