The expression 8 is a root of the function and 6 is not a root of the function

Checking if the numbers are roots of the polynomial functions

From the question, we have the following parameters that can be used in our computation:

f(x) = x² - 64

Checking if 8 is a root, we have

f(8) = 8² - 64

f(8) = 0

This means that 8 is a root of the function

Checking if 6 is a root, we have

f(6) = 6² - 64

f(6) = -28

This means that 6 is not a root of the function

Question

8 (is/isn't) a root of the polynomial function.

There are no real roots

Show your work by filling in the boxes below.

f(x) = x² - 64

f(8) = [ ]² - 64

f. 6 (is/isn't) a root of the polynomial function.

Show your work by filling in the boxes below

f(x) = x² - 64

f(6) = [ ]² - 64
