Question

love_to_love_you · Answer

Write each polynomial function in standard form, classify it by degree, and determine the end behavior of its graph. 
a. y=12-x^4

love_to_love_you · Answer

b. y = 2x^3 - 6x + 3x^2 - x^4 + 12

anonymous · Answer

Just put it order of highest degree to lowest degree

anonymous · Answer

a. for example is -x^4+12. And its 4th degree

love_to_love_you · Answer

I need to show all the work btw! :)

anonymous · Answer

Now for the graph ask yourself what does the graph of an even function look like?

love_to_love_you · Answer

It would be symmetrical right?

anonymous · Answer

yes but its a special shape. Do you know what x^2 looks like?

love_to_love_you · Answer

it's a symmetrical curve

love_to_love_you · Answer

I forget the name

love_to_love_you · Answer

quadratic. right?

anonymous · Answer

It's called a parabola and x^4 is the same symmetrical curve but x^4 is thinner

love_to_love_you · Answer

yes! parabola. ah, okay so how would I answer that then?

anonymous · Answer

Since in this case its negative x^4 it would be upside down

love_to_love_you · Answer

but what is the end behavior? what does that mean again?

love_to_love_you · Answer

-x^4+12; 4th degree; ??? 

I don't know what to write

anonymous · Answer

End behavior is describing what happens as the ends of the functions go off to infinity

anonymous · Answer

I'll see if i can find a video that explains it clearly
