Chapter 12: Q45. (page 637)

Write an equation for the parabola with the given vertex that passes through the given point.
Vertex $(3, 2)$
Point $(5, 6)$

Short Answer

Expert verified

The equation of the parabola is $y = {(x - 3)}^{2} + 2$ .

Step by step solution

Step 1. Given Information.

A given parabola has the vertex $(3, 2)$ and passes through the point $(5, 6)$ . The equation for the parabola is to be determined.

Step 2. Calculation.

The equation of a parabola with vertex $(h, k)$ is $y = a {(x - h)}^{2} + k$

Here h=3,k=2 and since the parabola passes through the point $(5, 6)$ , x=5,y=6

Plugging the values in the equation and solving for a:

$\begin{array}{l} y = a {(x 鈭� h)}^{2} + k \\ 6 = a {(5 鈭� 3)}^{2} + 2 \\ a {(5 鈭� 3)}^{2} = 6 鈭� 2 \\ a {(2)}^{2} = 4 \\ 4 a = 4 \\ a = 1 \end{array}$

Plugging back the value of a, h and k in the equation:

$\begin{array}{l} y = 1 {(x 鈭� 3)}^{2} + 2 \\ y = {(x 鈭� 3)}^{2} + 2 \end{array}$

Step 3. Conclusion.

Hence, the equation of the parabola is $y = {(x - 3)}^{2} + 2$ .
