Question

An Email to the Editor

Your favorite math magazine has recently published an article on their website about whether solving systems of non-linear equations is easier by graphing or algebraically.

You decide to write an email to the editor of the math magazine defending your opinion.

*Your email must be two to four paragraphs in length.
*You must express your opinion on which method is easiest.
*Provide at least three pieces of supporting evidence.
*Provide an additional graph of a system of non-linear equations that supports your viewpoint.

I am choosing algebraically,

Answer 1

But I'm at a loss as to where to find 3 pieces of supporting evidence, and I don't understand what they mean by "provide an additional graph of a system of non-linear equations that support your viewpoint". I would call my instructor, but she is on Christmas break of course. Any insight would be appreciated.

Answer 2

uhh, hi @Jordannyah :)

Answer 3

Hi

Answer 4

Any insight @phi ?

Answer 5

they want the 3 reasons you think algebraic is easier than graphic.
how about:
1) accuracy ... it is hard to read off the exact answer from a graph.
2) it is difficult to plot a complicated curve
3) The curves do not fit on the graph paper

***
Provide an additional graph of a system of non-linear equations that supports your viewpoint.

I think that means come up with a graph that shows one or more of the above reasons for why graphing is not the easiest way...

Answer 6

Here are some pointers.

Choose graphs, they are plottable.
Once when you plot the graph, all information can be easily analysed.
A bit of algebra knowledge is required
Certain systems do not have solutions, some have one solution, and others infinitely many solutions, and the graph shows all that, once drawn.
Attached is a graph for \[y=x ^{2} +2 & y= x+1\]

As you can see, the solutions are at the points of intersection.

Answer 7

\[y =x ^{2}+1\] and \[y=x+4\]

Answer 8

I thought by supporting evidence, they meant written articles or something. Thanks Phi... at least now I can quit looking for articles! lol

Thanks Mertich... now you've given me more to think about

@sleepyjess What was your paragraph for this answer ? please help

Answer 10

do you remember what lesson this is? @dxgx3
