Complete (a) and (b). lim x->∞ 7+x^2 22x^3 + 9x^2 (a) Use analytic methods to evaluate the limit. (If the limit is infinite, enter '∞' or '-∞', as appropriate. If the limit does not otherwise exist, enter DNE.)

Step 1
lim x->∞ (7 + x^2) / (22x^3 + 9x^2) = lim x->∞ (x^2(7/x^2 + 1)) / (x^3(22 + 9/x)) = lim x->∞ (7/x + 1) / (22 + 9/x) Show more…

Evaluating a limit In Exercises $43-62$ , (a) describe the type of indeterminate form (if any) that is obtained by direct substitution. (b) Evaluate the limit, using L'Hopital's Rule if necessary. (c) Use a graphing utility to graph the function and verify the result in part (b). $$\lim _{x \rightarrow \infty}\left(x-\sqrt{x^{2}+1}\right)$$
