Answer:
For the given functions f(x) and g(x) 
Step-by-step explanation:
Here, the given function are:

Now, simplifying for (f-g)(x) = f(x) - g(x):


Doing operation on LIKE TERMS, we get
f(x) - g(x) = 
Hence, for the given functions f(x) and g(x) 
Answer:
Step-by-step explanation:
-3b - 3b= (-3b)+(-3b)= -6b
Answer:
No, it is not a function because one of the x values have two different y values
Nine million, four hundred thousand, twenty three9
So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6. <span />
