Can anyone help me with this?

I don't need the answer given to me. Just an explanation on what to do, or any help at all would be really appreciated. I've tried Google and math sites with no help. This is really starting to frustrate me

Problem 37.

Sorry I forgot to mention it in the op. Been stuck on this for a while now

>>

From searching "find equation of parabola given 3 points" on Google:

http://jwilson.coe.uga.edu/emt668/emat6680.f99/jones/instructional%20unit/writingquads.html

Seems it's writing quadratic equations.

Thanks for trying, but it doesn't have to do with quadratic equations. I've came across similar articles while searching for help

>>

Equation is y = ax2+bx+c

Given the plot you have the system :

5 = a*22+b*2+c

-2 = a+b+c

-5=c

As the parabola passes by the points (2,5) (1,-2) (0,-5), x is the first coordinate and y the second and these coordinates are solutions to the equation (as the aquation represents the parabola)

You solve the system and find

a=2 b=1 c=-5

>>

5= a*2^2 +b*2+c (not 22 duh...)

>>

If you're wonder how he comes up with this, as his first note mentions, all parabolas are quadratic funcitons, and thus they can be written in the form y= a X^2 + bX + c, where a, b, c are coefficients.

He then takes that base and plugs values for X and Y (from each point given in the graph) and then solves the systems of three equations to find the coefficients, a b and c.

...calc?.... you're kidding or she's lying. This aint calc man. this is algebra. even in multivariant calc, where you come across tilts and other means things (fuck you elipsoids) you'd have to already be familiar with this stuff.

>>

>>34815

Probably lying. She's stupid as fuck.

Thank you again though guys, she's really happy its solved and she learned something

>>

>>34821

And now she is saying the answer is wrong, and the answer isn't a number

She's stupid isn't she?

>>

>>

>>34838

She's just stupid. And so am I for not being able to help her.

Thanks for all the help though, that's really nice of you

>>

>>34825

She needs to put the numbers determined in the general formula:

y = ax^2+bx+c with a=2 b=1 c=-5 becomes

y = 2x^2 + x - 5

>>

>>34843

Yup, that did it for her.

Thank you so much, she was really starting to freak out on me about this.

>>

>>34788

>they're having us do their trig homework now

what the fuck man

>>

>>34876

Not trig, and I was asking for help. I wouldn't have cried about it of nobody helped me. She just would've had to do it on her own like she is supposed to.

>>

>>34881

yup yup. its cool. I only come to /wsr/ for the math and science questions we get here. glad we could help

Eternal respect (and severe envy) to mathemagicians.

Kek,

This is so easy, you should be ashamed for asking this.
