The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except -3. Which of the following describes the domain of (g•f)(x)?
all real values except x-3 and the x for which fx) - 7
all real values except x-3 and the x for which f(x)-3
all real values except x - 7 and the x for which f(x) - 7
all real values except x7 and the x for which f(x) -3

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
