Answer:
-1
Step-by-step explanation:
4 unit rate is 124. 5 unit rate is 16 6 unit rate is 60
6!+7!+8!=(n)(6!)
calculate the individual values first:
6!=720
7!=5040
8!=40320
plug them into the equation:
720+5040+40320=n720
solve for n
5760+40320=n720
46080=n720
divide both sides by 720 to isolate n
46080/720=n720/720
64=n
The domain is all real numbers. (-infinity, infinity)
You can put any real number x value into the function.
