If f(x) = x + 2 and g(x) = x + 3, what is the constant term in (fg)(x)?

Answer and explanation

Correct answer: 6

Here (fg)(x) denotes the product f(x)g(x), not composition. Multiply the two functions: (fg)(x) = (x + 2)(x + 3). Applying distribution gives x^2 + 3x + 2x + 6, which simplifies to x^2 + 5x + 6. The constant term is the term independent of x, so it is 6 and option A is correct. There is also a quicker way to identify it: the constant term of a product comes from multiplying the constant terms of the factors, namely 2 × 3 = 6. Option B is the coefficient of x after combining like terms. Options C and D are the individual constant terms of f and g, not the constant term of their product. Recognizing the notation and combining like terms are both essential.
