The domain will be the numbers you can use for x and not get a undefined thing like division by 0 or square root of a negative number


(f*g)(x)=f(x) times g(x)=(3x+2) times (7x+6)=(3x+2)(7x+6)=21x^2+14x+18x+12=21x^2+32x+12

Illusion [34]

Answer:

6/7 = x/2

2 * 6 = 7 * x

12 = 7x

x = 12/7 bag of flour
