Solutions

Chapter 2, Problem 10RCC

a.

To determine

To find : the domain of f+g .

Expert Solution

Answer to Problem 10RCC

The domain of f+g = AB .

Explanation of Solution

Given information : The domain of f is given = A; the domain of g is given = B.

  f+g=f(x)+g(x)the domain of f+g is AB because both f(x) and g(x) must be defined.

b.

To determine

To find : the domain of fg .

Expert Solution

Answer to Problem 10RCC

The domain of fg = AB .

Explanation of Solution

Given information : The domain of f is given = A; the domain of g is given = B.

  fg=f(x)g(x)the domain of fg is AB because both f(x) and g(x) must be defined.

c.

To determine

To find : the domain of fg .

Expert Solution

Answer to Problem 10RCC

The domain of fg = AB|g(x)0 .

Explanation of Solution

Given information : The domain of f is given = A; the domain of g is given = B.

  fg=f(x)g(x)the domain of fg is AB | f(x)  0 because both f(x) and g(x) must be defined.
