Given functions f and g, Find f-g.
f(x)=6x-2, g(x)=9x-6

a)3x-4
b)-3x+4
c)-3x-8
d)15x-8

Sagot :

Answer:

b)-3x+4

Step-by-step explanation:

f(x)=6x-2, g(x)=9x-6

f - g means to subtract the two functions so:

f - g = (6x - 2) - (9x - 6)                

first, distribute the negative sign to (9x - 6)

f - g = 6x - 2 - 9x + 6

then, combine like terms:

f - g = -3x + 4
