Question 1125466: Describe the end behavior using limit notation for the following functions:
𝑓(𝑥) = −2𝑥^4 − 3𝑥^3 + 3𝑥 − 5
𝑓(𝑥) = (5𝑥+3)/(2𝑥−7)
Thank you!

--------------------------------
𝑓(𝑥) = −2𝑥^4 − 3𝑥^3 + 3𝑥 − 5
--------------------------------

Use your knowledge of polynomial functions.



----------------------
𝑓(𝑥) = (5𝑥+3)/(2𝑥−7)
----------------------

x to the extreme left or to the extreme right, make the function increasingly closer to 5%2F2, because the terms in the top and bottom make the 5x and the 2x increasingly more important, and the 3 and the -7 increasingly LESS important.
