I was reading the list of upcoming business meetings in a weekly email from The Seattle Times, when a meeting announcement caught my attention. The presenter was going to talk on a topic that interests me--the steps in growing one's business. I often weigh the advantages of getting bigger vs. staying small as a business, so I thought I would register for her talk. But I wanted to know more about the presenter, so I clicked the link to her blog. That's when things went wrong. Her latest blog entry was one huge paragraph 41 lines long. Can you imagine her 325 words in one big block? You don't have to--I have created a 325-word block of text here. I forced myself to read her paragraph. Hiding in it was some good information, but that info could not undo the negative impression. If that big, bad paragraph represents the woman's communication skills, I would be much better off finding another resource.I was reading the list of upcoming business meetings in a weekly email from The Seattle Times, when a meeting announcement caught my attention.

Explain the special pattern for sketching a parabola
Lady bird [3.3K]

Answer:

the parabola can be written as:

f(x) = y = a*x^2 + b*x + c

first step.

find the vertex at:

x  = -b/2a

the vertex will be the point (-b/2a, f(-b/2a))

now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.

The next step is to see if we have real roots by using the Bhaskara's equation:

x =  \frac{-b +-\sqrt{b^2 -4ac} }{2a}

Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.

If you do not have any real roots, you can feed into the parabola some different values of x around the vertex

for example at:

x =  (-b/2a) + 1 and x =  (-b/2a) - 1

those two values should give the same value of y, and now you can connect the vertex with those two points.

If you want a more exact drawing, you can add more points (like x =  (-b/2a) + 3 and x =  (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.
