A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
Before we delve into how to have the focus of an eagle, you should realize the daily habits which distract the heck out of you. Many of these distractions might seem minuscule by themselves. Wait until you sum them up and they total up to a mammoth value. Let's look at the so-called 'minor' distractions. Smartphone usage. Editing your block list. You retain total control over which websites and applications Focus blocks. To edit your lists, click over to the Blocking tab. Use the drop-down menu to choose between the lists of websites you want to block and allow while the app is active. ★ Scheduling With Focus, you can create schedules, such as 'Block Twitter and Youtube from Monday to Friday from 8AM to 5PM' or 'Block social media after 10PM every day'. ★ Maximum time per day If you want to browse a useful site (ex: Facebook) each day, but not for too long, you can easily do so by setting a maximum time allowed per day. Simply click the Focus icon in the menubar located on the top right. You will be presented with the following menu: You can choose to turn on the app and start blocking distractions for a preset amount of time by clicking Focus for 10 minutes, 30 minutes, or 1 hour. You can also click Custom focus to have the app run for a specific time.

The focus lies on the axis of symmetry of the parabola.
Finding the focus of a parabola given its equation
If you have the equation of a parabola in vertex form y=a(x−h)2+k, then the vertex is at (h,k) and the focus is (h,k+14a).
Notice that here we are working with a parabola with a vertical axis of symmetry, so the x-coordinate of the focus is the same as the x-coordinate of the vertex.
Example 1:
Find the focus of the parabola y=18x2.
Here h=0and k=0, so the vertex is at the origin. The coordinates of the focus are (h,k+14a) or (0,0+14a).
Since a=18, we have
14a=1(12)
=2 Poster 1 6 4.
The focus is at (0,2).
Example 2:
Find the focus of the parabola y=−(x−3)2−2.

Here h=3 and k=−2, so the vertex is at (3,−2). The coordinates of the focus are (h,k+14a) or (3,−2+14a).

Here a=−1, so
−2+14a=−2−14
=−2.25
The focus is at (3,−2.25).
