Answer:
A
Step-by-step explanation:
Answer:
The option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>
Step-by-step explanation:
As the domain of f(x) is the set of all real values except 7. So it can be written as follows:
Domain of f(x) = { x ∈ R | x ≠ 7}
As the domain of g(x) is the set of all real values except -3. So it can be written as follows:
Domain of g(x) = { x ∈ R | x ≠ -3}
It is a common rule that the domain of a composite function (gºf)(x) will be the set of those input x in the domain of f for which f(x) is in the domain of g.
So, the option is: <em>all real values except x = 7 and the x for which f(x) = -3</em>

Answer:
constant of variation
Step-by-step explanation:
Constant of variation and constant of proportionality mean the same and they are used in variations.
For instance:
In the above equation, y varies directly as x and the constant of proportionality or variation is 2.
<em>It is often represented with k (though, other alphabets can also be used)</em>
Answer:
b = 8 and b = 8
Step-by-step explanation:
f(b) =b² − 16b + 64 is set equal to zero and solved for b:
f(b) =b² − 16b + 64 = 0
This quadratic can be factored, as follows: f(b) = (b - 8)(b - 8) = (b - 8)² = 0
There are two real, equal zeros: b = 8 and b = 8.
A) Addition
because they already sovled and gave the right answer which is -2. you don´t need to add anything else. it´s already done.
