Question

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

Addition
Subtraction
Multiplication
Two operations result in the same coefficien

Answer 1

The answer is Multiplication.

Explanation:

The coefficient of the x term in f(x) is 2, and the coefficient of the x term in g(x) is 2. When we add or subtract the two functions, the coefficient of the x term remains 2. However, when we multiply the two functions, the coefficient of the x term becomes 4. Therefore, multiplication results in the largest coefficient on the x term.

Here is the solution for each of the operations:

Addition: f(x) + g(x) = (2x −1) + (2x + 4) = 4x + 3

Subtraction: f(x) - g(x) = (2x −1) - (2x + 4) = -5

Multiplication: f(x) * g(x) = (2x −1) * (2x + 4) = 4x^2 + 6x - 4

As you can see, the coefficient of the x term in f(x) * g(x) is 4, which is larger than the coefficients of the x terms in f(x) + g(x) and f(x) - g(x). Therefore, multiplication results in the largest coefficient on the x term.
