According to the Rational Root Theorem, Negative two-fifths is a potential rational root of which function? f(x) = 4x4 – 7x2 + x + 25
f(x) = 9x4 – 7x2 + x + 10
f(x) = 10x4 – 7x2 + x + 9
f(x) = 25x4 – 7x2 + x + 4

Step-by-step explanation:

To find the right answer, we just need to replace the given root in each expression and see which one gives zero.

Therefore, neither expression satisfies the given rational root.
