Question

Given the functions f(x) = - 4x - 1 and g(x) = 2x + 4, which operation results in the smallest coefficient on the x term?

Addition

Subtraction

Multiplication

Two operations result in the same coefficient

Answer 1

Answer: mulitplication

Explanation:

Answer 2

Perform the operation in the choices to determine the coefficients of the terms.

(Addition) -4x - 1 + 2x + 4 = -2x + 3
(Subtraction) -4x - 1 - (2x + 4) = -6x - 5
(Multiplication) (-4x - 1)(2x + 4) = -8x² -18x -4

Thus, the answer is multiplication as it gives a numerical coefficient equal to -18.
