$(f + g)(x) = - 10 \sqrt[3]{2x} \: \: \: (f + g)( - 4) = 20$

$(f - g)(x) =12 \sqrt[3]{2x} \: \: \: (f - g)( - 4) = - 24$

The domain of (f+g)(x) is all real numbers.

The domain of (f-g)(x) is all real numbers.

Step-by-step explanation:

The given functions are

$f(x) = \sqrt[3]{2x}$

and

$g(x) =- 11\sqrt[3]{2x}$

By the algebraic properties of polynomial functions:

(f + g)(x) = f(x) + g(x)

$(f + g)(x) = \sqrt[3]{2x} + - 11 \sqrt[3]{2x}$

This becomes:

$(f + g)(x) = \sqrt[3]{2x} - 11 \sqrt[3]{2x}$

We subtract to obtain:

$(f + g)(x) = - 10 \sqrt[3]{2x}$

Also

(f - g)(x) = f(x) - g(x)

$(f - g)(x) = \sqrt[3]{2x} - - 11 \sqrt[3]{2x}$

$(f - g)(x) = \sqrt[3]{2x} + 11 \sqrt[3]{2x}$

$(f - g)(x) = 12\sqrt[3]{2x}$

When x=-4

$(f + g)( - 4) = - 10\sqrt[3]{2 \times - 4}$

$(f + g)( - 4) = - 10\sqrt[3]{ - 8}$

$(f + g)( - 4) = - 10 \times - 2 = 20$

Then also;

$(f - g)( - 4) = 12\sqrt[3]{ - 8}$

$(f - g)( - 4) = 12 \times - 2 = - 24$

The domain refers to the values that makes the function defined.

Both are cube root functions and are defined for all real numbers.

The domain of (f+g)(x) is all real numbers.

The domain of (f-g)(x) is all real numbers.

i'm not sure what you mean but in todays world there is a lot of women that are the bread winners in the family. there is a lot more single mothers now that are going back to get an education which is boosting the economy. i believe there has been a boost in the economy due to women the cosmetic industry is boosting, chemist, the sky is becoming the limit for women in todays economy. most women are also putting off having kids just to make sure they have a education. i don't know how these two relate though to scriptures because it's not the way the lord wanted it. the man is suppose to be the bread winner and due to social media and the easy access we have there is a lot of cheating going on.
