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>

We have to find two solutions of quadratic equation.
Using addition property of equality
(By using factorization method)
Substitute each factor equal to 0
and
and
Hence, two solutions of quadratic equation are
v=-5 and v=3
Answer:
Alan spent $7.24 in total.
Step-by-step explanation:
2 1/2 pounds of bananas is equal to 2.5 pounds of bananas (decimal)
2.5 (pounds of bananas) x 1.06 (unit cost for 1 pound of bananas) = $2.65
4 1/2 pounds of peaches is equal to 4.5 pounds of peaches (decimal)
4.5 (pounds of peaches) x 1.02 (unit cost for 1 pound of peaches) = $4.59
4.59 + 2.65 = $7.24 spent in total
