( please help I really need it )Joan represents the height at which a sea gull is flying at +4 feet and the depth at which a fis

h is swimming at −3 feet on a number line, where 0 represents the surface of the water. Which of these explains whether the sea gull or the fish is closer to the surface of the water?
The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4.


The fish is closer to the surface of the water because |+4| = 4 and − |−3| = −3, and −3 < 4.


The sea gull is closer to the surface of the water because |+4| = −4 and |−3| = −3, and −3 > −4.


The sea gull is closer to the surface of the water because |+4| = 4 and − |−3| = 3, and 4 > 3.

Answer:

The fish is closer to the surface of the water because |+4| = 4 and |−3| = 3, and 3 < 4.

Step-by-step explanation:

The answer is this because they are finding the absolute value. Because 3 is less than 4, that means that it isn't as far away from zero on the number line. This is the only answer where the absolute value and the object is correct.

Answer:

look below

Step-by-step explanation:

y = 2 (x + 3)^2 - 2

Geometric figure:  parabola

Alternate forms:

y = 2 (x + 2) (x + 4)

y = 2 (x^2 + 6 x + 8)

-2 x^2 - 12 x + y - 16 = 0

Expanded form:

y = 2 x^2 + 12 x + 16

Roots:

x = -4

x = -2

<u>Properties as a real function: </u>

Domain - R (all real numbers)

Range - {y element R : y>=-2}

Partial derivatives:

d/dx(2 (x + 3)^2 - 2) = 4 (x + 3)

d/dy(2 (x + 3)^2 - 2) = 0

Implicit derivatives:

(dx(y))/(dy) = 1/(12 + 4 x)

(dy(x))/(dx) = 4 (3 + x)

Global minimum:

min{2 (x + 3)^2 - 2} = -2 at x = -3
