Answer:
Correct option: Third one
Step-by-step explanation:
Let's analyse each sentence:
"Both x = -8 and x = 8 are roots of f(x)"
False, we can't affirm that x = 8 is a root of f(x) with the information given.
"Neither x = -8 nor x = 8 is a root of f(x)"
False, because x = -8 is a root of f(x), because the factor (x + 8) would be zero, and it is multiplying the rest of the function, so the final value would be zero.
"f(-8) = 0"
True, because x = -8 is a root, and the factor x + 8 will be zero and will multiply the other factors of f(x)
"f(8) = 0"
False, because x = 8 is not a root of f(x)
So the correct option is the third one
