Problem 9E

Show that $$x^{2}+4 x+17$$ is $$O\left(x^{3}\right)$$ but that $$x^{3}$$ is not $$O\left(x^{2}+4 x+17\right)$$

Step-by-Step Solution:

Step 1 of 2

Let us assume that x > 1 then So, the first term that is will influence.

Then, instead of we can write as . Because will grow as slow as And the second term is also an influence because x will grow as slow as Hence, Where n = 3, C = 22 and k = 1

So the growth of the function is O( ).

Hence, it is proved that has the growth of function O( ).

Step 2 of 2
