# Math Help - Right end behavior modelss, HELP PLZ!

1. ## Right end behavior modelss, HELP PLZ!

For the function y= 3x^2 -5x + 7^ -x

how would you find a simple basic function right end behavior model

and the left end behavior model??

for the right I got 3x^2 but that is left and right b/c its a parabola so do i put restrictions on it or is that okay??

2. For very large, positive, x, $e^x$ goes to 0 and the function acts like $3x^2- 5x$. For very large, negative, x, $e^x$ dominates.
