A whale jumps above the surface of the ocean and then dives back under. Its height above the surface can be sketched on a set of axes where x represents time and y represents distance above or below the surface. The domain for this graph is best represented using a set of:
Integers
Positive Integers
Positive real numbers
Real numbers

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
