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
