Tems11 [23]

An example would be using points

it is a function because each input has only one input.

or

using the vertical line test none of the points are on the same line

What is the equation of the parabola with focus (3, 0) and directrix x = –3?

nikitadnepr [17]

Answer:

x = $\frac{1}{12}$ y²

Step-by-step explanation:

Any point (x, y ) on the parabola is equidistant from the focus and the directrix

Using the distance formula, then

$\sqrt{(x-3)^2+(y-0)^2}$ = | x + 3 |

Squaring both sides

(x - 3)² + y² = (x + 3)² ← expanding both sides

x² - 6x + 9 + y² = x² + 6x + 9 ← subtract x² + 6x + 9 from both sides

- 12x + y² = 0 ( subtract y² from both sides )

- 12x = - y² ( divide both sides by - 12 )

x = $\frac{1}{12}$ y²
