Question 1048811
If you were to expand it out, you would get *[tex \large f(x) = -x^7 + \ldots] where ... represents functions that grow asymptotically slower than -x^7 (we can also write it as *[tex \large f(x) = -x^7 + O(x^6)] using big O notation).


Therefore for large values of |x|, f(x) is approximately -x^7.
