You could make a table and pick some points. Say, 2,1,0,1,2 ?

For example For 10 i am getting 9 for y and for 10 i am getting 7.6 for y. This means the graph is not symmetrical

that just means its not symmetrical about the y axis choose x=0,20,40,60,80,100,120 you'll find it symmetrical about x=60

I have another question. SO this was not symmetrical along the y axis and when I was making my table of values, I was not able to get a cororect parabola. How can I fnid out wether I should make the x values all positive or negative so I do get the symmetrical point in my table of values?

it says "use graphing technology" so you are allowed to cheat http://www.wolframalpha.com/input/?i=x^2%2F144%2B5%2F6x++domain+0..120

i meant multiply by 144
 one year ago

satellite73 Group TitleBest ResponseYou've already chosen the best response.1
\[\frac{1}{144}x^2+\frac{5}{6}x=0\] multiply by 144 to get \[x^2120x=0\] factor as \[x(x120)=0\]
