Question
Remington wanted to write the parabolic equation with the three points (0,3) , (−3,2) , and (3,4) . Is this possible? What does the result mean?(1 point) Responses This is possible. The parabolic equation is y=13x2+3. This is possible. The parabolic equation is y equals Start Fraction 1 over 3 End Fraction x squared plus 3 . This is not possible. Since a=0, only higher degree equations can be written. This is not possible. Since a equals 0 , only higher degree equations can be written. This is possible. The parabolic equation is y=23x2+73x+3. This is possible. The parabolic equation is y equals Start Fraction 2 over 3 End Fraction x squared plus Start Fraction 7 over 3 End Fraction x plus 3 . This is not possible. Since a=0, the result is a linear equation, y=13x+3.

To determine if a parabolic equation can be written with the given three points \((0, 3)\), \((-3, 2)\), and \((3, 4)\), we can use the standard form of a parabolic equation, which is \(y = ax^2 + bx + c\). Since we have three points, we can set up a system of equations to find the values of \(a\), \(b\), and \(c\).
1. Using the point \((0, 3)\):
\[
3 = a(0)^2 + b(0) + c \Rightarrow c = 3.
\]
2. Using the point \((-3, 2)\):
\[
2 = a(-3)^2 + b(-3) + 3 \Rightarrow 2 = 9a - 3b + 3 \Rightarrow 9a - 3b = -1 \quad \text{(Eq. 1)}.
\]
3. Using the point \((3, 4)\):
\[
4 = a(3)^2 + b(3) + 3 \Rightarrow 4 = 9a + 3b + 3 \Rightarrow 9a + 3b = 1 \quad \text{(Eq. 2)}.
\]
Now we can solve the system of equations formed by Eq. 1 and Eq. 2:
From Eq. 1:
\[
9a - 3b = -1 \quad \Rightarrow \quad 3b = 9a + 1 \quad \Rightarrow \quad b = 3a + \frac{1}{3}.
\]
Substituting \(b\) into Eq. 2:
\[
9a + 3(3a + \frac{1}{3}) = 1 \Rightarrow 9a + 9a + 1 = 1 \Rightarrow 18a + 1 = 1 \Rightarrow 18a = 0 \Rightarrow a = 0.
\]
If \(a = 0\), the equation becomes \(y = bx + c\), which is a linear equation. Substituting back,
\[
b = 3(0) + \frac{1}{3} = \frac{1}{3} \Rightarrow y = \frac{1}{3}x + 3.
\]
Now the potential parabolic equation cannot be formed as \(a = 0\) indicates a linear function rather than a quadratic one.
Thus, we can conclude:
**This is not possible. Since \(a = 0\), only higher degree equations can be written.**

\]
If \(a = 0\), the equation becomes \(y = bx + c\), which is a linear equation. Substituting back,
\[
b = 3(0) + \frac{1}{3} = \frac{1}{3} \Rightarrow y = \frac{1}{3}x + 3.
