Standard Form Quadratic Function Practice Problems

To solve this problem, we will substitute the given values into the standard quadratic form:

• Step 1: Identify the formula to use. We need the standard form of a quadratic function, which is $y = ax^2 + bx + c$.
• Step 2: Substitute the given parameters into the formula:
  $a = -3$, $b = 3$, and $c = 7$.
• Step 3: Perform the substitution:
  Substituting in, we get $y = -3x^2 + 3x + 7$.

Therefore, the correct algebraic expression is $-3x^2 + 3x + 7$.

This corresponds to choice 2 of the multiple-choice options provided.

To solve this problem, we'll use the following steps:

• Step 1: Substitute $a = 0$, $b = 1$, $c = 0$ into the quadratic equation $y = ax^2 + bx + c$.
• Step 2: Simplify the expression based on these substitutions.

Working through these steps:

Step 1: Start with the expression $y = ax^2 + bx + c$.

Since $a = 0$, then $ax^2 = 0 \cdot x^2 = 0$.
Since $b = 1$, then $bx = 1 \cdot x = x$.
Since $c = 0$, then $c = 0$.

Step 2: Plug these values into the equation:

The expression simplifies to:

Thus, the simplified algebraic expression is $y = x$.

Therefore, the solution to the problem is $x$.

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:

$-x^2$

To solve this problem, let's proceed with the construction of the quadratic expression:

• Step 1: Recognize the standard form of a quadratic expression, which is $ax^2 + bx + c$.
• Step 2: Substitute the given values into this formula:
  • $a = 1$
  • $b = 16$
  • $c = 64$
  Plugging in these values, we determine the expression to be $1x^2 + 16x + 64$, which simplifies to $x^2 + 16x + 64$.

Thus, the algebraic expression we derive from these parameters is the quadratic expression:

$x^2 + 16x + 64$

This matches the correct choice provided in the given multiple-choice options.

To determine the algebraic expression, we start with the standard quadratic function:

$y = ax^2 + bx + c$

Given the values:

• $a = -1$
• $b = 1$
• $c = 0$

We substitute these into the formula:

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

Simplifying the expression gives:

$y = -x^2 + x$

Thus, the algebraic expression, when these parameters are substituted, is:

The solution to the problem is $\boxed{-x^2 + x}$.
