Q. A parabola opening up or down has vertex

(0,0)

and passes through

(12,12)

. Write its equation in vertex form.

\newline

Simplify any fractions.

\newline

______

Vertex Form of Parabola: What is the vertex form of the parabola? $\newline$ Vertex form of parabola: $y = a(x - h)^2 + k$
Equation at Vertex ( $0$ , $0$ ): What is the equation of a parabola with a vertex at $(0, 0)$ ? $\newline$ Substitute $0$ for $h$ and $0$ for $k$ in vertex form. $\newline$ $y = a(x - 0)^2 + 0$ $\newline$ $y = ax^2$
Substitute $(12, 12)$ : $y = ax^2$ $\newline$ Replace the variables with $(12, 12)$ in the equation. $\newline$ Substitute $12$ for $x$ and $12$ for $y$ . $\newline$ $12 = a(12)^2$ $\newline$ $12 = 144a$
Solve for $a$ : $12 = 144a$ Solve for $a$ . $\frac{12}{144} = a$ $\frac{1}{12} = a$
Equation with $a = \frac{1}{12}$ : $y = ax^2$ $\newline$ What is the equation of the parabola if $a = \frac{1}{12}$ ? $\newline$ Substitute $\frac{1}{12}$ for $a$ . $\newline$ $y = \left(\frac{1}{12}\right)x^2$ $\newline$ Vertex form of parabola: $y = \left(\frac{1}{12}\right)x^2$
