Standard Form Quadratic Function Practice Problems

To solve this problem, we will follow these steps:

• Step 1: Identify the given parameters $a = 3$, $b = 6$, $c = 9$.
• Step 2: Use the standard formula for a quadratic expression, which is $y = ax^2 + bx + c$.
• Step 3: Substitute the given values into this formula.

Now, let's work through each step:
Step 1: We have the parameters $a = 3$, $b = 6$, $c = 9$.
Step 2: The standard form of a quadratic equation is $y = ax^2 + bx + c$.
Step 3: Substituting the given values into the expression, we get:

$y = 3x^2 + 6x + 9$

Therefore, the algebraic expression based on the given parameters is:

$3x^2 + 6x + 9$.

To solve this problem, we'll follow these steps:

• Step 1: Identify and substitute the values of $a$, $b$, and $c$ into the equation $y = ax^2 + bx + c$.
• Step 2: Simplify the equation to obtain the required expression.
• Step 3: Compare the simplified expression with the provided multiple-choice answers.

Let's work through each step:

Step 1: The given coefficients are $a = \frac{1}{2}$, $b = \frac{1}{2}$, and $c = \frac{1}{2}$. Substitute these values into the standard quadratic form $y = ax^2 + bx + c$:

$y = \frac{1}{2}x^2 + \frac{1}{2}x + \frac{1}{2}$

Step 2: The expression is already simplified. The coefficients are correctly substituted, and no further simplification is needed:

$y = \frac{x^2}{2} + \frac{x}{2} + \frac{1}{2}$

Step 3: Compare this expression to the provided multiple-choice options. The correct match is:

Choice 1: $\frac{x^2}{2} + \frac{x}{2} + \frac{1}{2}$

Therefore, the algebraic expression is $\frac{x^2}{2} + \frac{x}{2} + \frac{1}{2}$.

To solve this problem, we'll follow the steps outlined:

• Step 1: Identify the given values for the quadratic function's parameters: $a = 2$, $b = \frac{1}{2}$, and $c = 4$.
• Step 2: Apply these values to the standard quadratic form $y = ax^2 + bx + c$.
• Step 3: Substitute the values to construct the algebraic expression.

Now, let's proceed with these steps:

Given the standard form of a quadratic expression $y = ax^2 + bx + c$:

Substituting the values, we obtain:

$y = 2x^2 + \frac{1}{2}x + 4$

Therefore, the correct algebraic expression for the quadratic function is $2x^2 + \frac{1}{2}x + 4$.

To solve this problem, we need to create a quadratic expression using the provided values for $a$, $b$, and $c$.

The standard form of a quadratic function is:

$y = ax^2 + bx + c$

Given the values:

• $a = 2$
• $b = 2$
• $c = 2$

We substitute these values into the standard quadratic formula:

$y = 2x^2 + 2x + 2$

Therefore, the algebraic expression for the quadratic function based on the provided parameters is $2x^2 + 2x + 2$.

The correct answer is choice 1: $2x^2 + 2x + 2$.

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.
