question 79

Multiple Choice

For the given functions f and g, find the requested function and state its domain. Write the domain in interval notation.
- $f ( x ) = 16 - x ^ { 2 } ; g ( x ) = 4 - x ; \quad$ Find $f + g$

• A) \(( f + g ) ( x ) = - x ^ { 2 } - x + 20 ; ( \infty , \infty )\)
• B) \(( f + g ) ( x ) = x ^ { 3 } - 4 x ^ { 2 } - 16 x + 64 ; ( \infty , \infty )\)
• C) \(( f + g ) ( x ) = 4 + x ; ( \infty , - 4 ) \cup ( - 4 , \infty )\)
• D) \(( f + g ) ( x ) = - x ^ { 2 } + x + 12 ; ( \infty , \infty )\)

Definitions:

Blood Pressure

Blood pressure is the force exerted by circulating blood on the walls of the body's arteries, important for maintaining blood flow through the body.

Pulmonary Circulations

The part of the circulatory system specifically responsible for carrying deoxygenated blood from the right side of the heart to the lungs and returning oxygenated blood back to the heart.

Systemic Circulations

The component of the cardiovascular system responsible for transporting oxygen-rich blood from the heart to the body and bringing oxygen-poor blood back to the heart.

Blood Supply

The provision of blood to different parts of the body, facilitated by the circulatory system.
