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.
The least squares method will minimize the sum of squares error when describing the equation that best fits the ordered pairs.
There is no distributive property in this problem. Distributive property is only used when it looks like this 5(7+1). You distribute the 5 to the 7 and the 1. But in that problem you can’t. You just add.
