Question

For the function y=3x^2-5x+7x^-1, find a simple basic function right end behavior model?

Answer 1

y = 3x^2 - 5x

Answer 2

how did you get that answer? thanks!

Answer 3

as x tends to infinity, 7x^-1 tends to 0. So the function tends to 3x^2 - 5x

Answer 4

Okay what if the question asks: a simple basic function left end behavior model?

Answer 5

same function as right end behavior

Answer 6

so are the functions you wrote the left and right end behavior functions?

Answer 7

for large amount of x , they have almost same behavior

Answer 8

now i give you an example
it clearly shows the same behavior of y=x^2 and y=x^2+1/x for large x (end behavior)

Answer 9

oohh okay thank you soo much!
