Answer:
you should know this. you tell me how many?
Answer:
Domain = R- {0,4}
Step-by-step explanation:




In order to function (f*g)x to be defined , the Denominator must not be equal to zero.
Hence
x ≠ 0
(x-4) ≠ 0 ⇒ x≠4
Hence (f*g)x is defined for all values of x except 0 and 4
Hence Domain = R- {0,4}
You can't really get your answer like 7/8 to 3/4 because 7 doesn't go into 3. hope that helped
Multiply the top and bottom by 2
6/14 = 12/28
now solving for the 2nd part is more difficult i would use cross multiply and divide . Multiply 6 and 12 which equals 72 then divide by 14 which will get you 5.142857 or 5 36/7= 71/14
Pretty sure it’s number 1
