A turtle resides in the ocean water and on land. When underwater, the turtle reaches a depth of 3,000 feet below sea level. When on land, the turtles are at sea level. Select the inequality that shows the relationship between the depth the turtle swims and reaches when on land.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

there is no graph so i cant sorry
