The answer is B.

Step-by-step explanation:

Since f(x) = 4x + 1 and g(x) = x^2 - 5, 4x + 1 can be substituted for f and x^2 - 5 can be substituted for g in the equation (g/f)(x). Keep in mind that the x after (g/f) is just saying that (g/f) is a function of x, which means that it changes depending on the value of x. The x is not involved in any of the calculations, only the g and f values are. Knowing that x^2 - 5 substitutes for g and 4x + 1 substitutes for f, the equation would be (x^2 - 5/4x + 1) which means that answers A and C can be eliminated. After that, the only remaining answers are B and D, and the only difference between them is that B says that x cannot be equal to -1/4. This is true because the denominator of a fraction cannot be equal to 0 and plugging in -1/4 for x would give 4(-1/4) + 1 which would be equal to -1 + 1 which is equal to 0. The reason why a denominator of a fraction cannot be equal to 0 is because it is impossible to divide by 0 (unless the numerator is also 0) as dividing by 0 will not grant an answer because no matter how many times it is multiplied it will not ever equal the number that it was trying to go into.

It is the letter B here is why f(x) = 4x + 1 and g(x) = x^2 - 5, 4x + 1
