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.

think about it deeply and passionately about this property
