Third choice
Step-by-step explanation:
The domain of f(x) is the set of all real values except 7, i.e 
and the domain of g(x) is the set of all real values except -3, i.e 
The domain of 
is the set of all real numbers x in the domain of 
such that 
is in the domain of 
.
However any numbers that are excluded from the domain of f must also be excluded from the domain of .
Therefore the correct choice is all real values except x=7 and the x for which f(x) =7
Answer:i
Step-by-step explanation:
Total coin = 36
Let the no. Of quarter = x
No. Of nickel = 1/15 × x = x/15
So, x + x/15 = 36
Multiply each terms by 15
15x + x = 540
16x = 540
x = 540/16
x = 33.75
Nickel is x/15 = 33.75/15 = 2.25
