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.

did it in my copy but it took too long to upload so i gave up. sry
Answer:
g=-6, x=-1
Step-by-step explanation:
23=−4g−1
Step 1: Flip the equation.
−4g−1=23
Step 2: Add 1 to both sides
−4g−1+1=23+1
−4g=24
Step 3: Divide both sides by -4
−4/-4g
=24/-4
g=-6
--------------------------------------------------------------------------------------------------------------
13=−4x+9
Step 1: Flip the equation
−4x+9=13
Step 2: Subtract 9 from both sides
−4x+9−9=13−9
−4x=4
Step 3: Divide both sides by -4
−4x/-4=
4/-4
x=−1
this might be wrong but i would say B. hope this helps :) sorry if wrong
Answer:
B
Step-by-step explanation:
I found this out my pluging in the points from B into the two each equation
Hope this helped
