The value 5 is an upper bound for the zeros of the function shown below. f(x)= x4 + x3 – 11.x2 – 9x + 18
A. True

B. False

The given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

Step-by-step explanation:

Given

We know the rational zeros theorem such as:

if is a zero of the function ,

then .

As the is a polynomial of degree , hence it can not have more than real zeros.

Let us put certain values in the function,

, , , ,

, , , ,

From the above calculation results, we determined that zeros as

and .

Hence, we can check that

Observe that,

, increases rapidly, so there will be no zeros for .

Therefore, the given statement that value 5 is an upper bound for the zeros of the function f(x) = x⁴ + x³ - 11x² - 9x + 18  will be true.

since both sides equal, there are infinitely many olutions.
