Answer:
Step-by-step explanation:
We are given f(x) and g(x)
1. (f+g)(x)
(f+g)(x) = f(x) + g(x)
=
=
Domain : All real numbers as it there exists a value of (f+g)(x) f every x .
2. (f-g)(x)
(f-g)(x) = f(x)-g(x)
=
=
Domain : All real numbers as it there exists a value of (f-g)(x) f every x .
Part 3 .
Domain : In this case we see that the function is not defined for values of x for which the denominator becomes 0 or less than zero . Hence only those values of x are defined for which
or
Hence taking square roots on both sides and solving inequality we get.
Answer:
A) LEngth of FG is 2 units
Step-by-step explanation:
Considering the diagram attached below.
Reflection of any polygon does not affects its length.
As it is given both polygons are reflection of each other so their sides are congruent.
AB ≅ EF = 3 units
BC ≅ FG = 2 units
CD ≅ GH = 2.2 units
DA ≅ HE = 3.2 units
