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:
Dont understands the lay out of this question.

Please Explain in details.
Answer:
There are 2 solutions: x = -5, 9.
Step-by-step explanation:
(x-2)^2 =49
Take square roots of both sides:
x - 2 = +/- 7
So x - 2 = 7 gives x = 9 , and
x - 2 = -7 gives x = -5.
100 I guess because if 16*10 is 160 then 10*10 is 100
