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
