Question

What is end behavior?

Answer 1

"end behavior" (when applied to a function) is the nature of the value as the function argument approaches `+oo` and `-oo`

Explanation:

For example:

[1] The end behavior of `f(x)=x^2`
is `f(x)rarr +oo` (as `xrarr+-oo`)

[2] The end behavior of `g(x) = 1/x+27`
is `g(x)rarr 27` (as `xrarr+-oo`)

[3] The end behavior of `h(x) = x^3`
is `h(x)rarr +oo" as "xrarr+oo`
and `h(x)rarr-oo" as "xrarr-oo`

[4]The end behavior of `i(x) = cos(x)`
is `i(x)` oscillates between `+1` and `-1` (as `xrarr+-oo`)
