help please!

Given the functions f(x) = -2x - 1 and g(x) = -3x + 4, which operation results in the smallest coefficient on the x term?

A.Two operations result in the same coefficient
B. Subtraction
C.Multiplication
D.Addition

Answer 1

so i assume you are looking at
f - g , f + g , f * g

Answer 2

@perl yeap

Answer 3

f*g = ( -2x -1 ) ( -3x + 4) = 6x^2 +3x -8x - 4 = 6x^2 -5x - 4

f+ g = (-2x - 1 ) + (-3x + 4) = -5x - 3 .
so the answer is two of them

Answer 4

f*g = ( -2x -1 ) ( -3x + 4) = 6x^2 +3x -8x - 4 = 6x^2 -5x - 4
f+ g = (-2x - 1 ) + (-3x + 4) = -5x - 3
f - g = ( -2 x - 1 ) - (-3x + 4) = -2x - 1 + 3x - 4 = x - 5

so we have two expression with -5x

Answer 5

@perl thank you!
