I need to find the parent function and compare and contrast the domain and range of the parent function.
denpristay [2]
The parent function is f(x) = x^3 with domain = all real numbers and range = all real numbers.

The given function is f(x) = x^3 - 2 with domain = all real numbers and range = all real numbers.

how many minutes is it before 12 noon if 20 minutes ago it was three times as many minutes after 9 am
Hunter-Best [27]
First, change everything into minutes.
12 noon is 12 by 60 which = 720 minutes.
9am is 9 by 12 which = 540 minutes.
X is now your number of minutes before noon.So noon - x is the next step:
720 - x
20 minutes ago it was 720 - x - 20
720 - x - 20= 540 + 3x (3x because you're looking for 3 times as many minutes)
720 - 20 - 540=4x (you combine all the like numbers and variables) 
160 = 4x
160/4= x
40 = x
Your answer is 40 minutes

The square shown has a perimeter of 32 units. The square is rotated about line k. What shape is created by the rotation and what
harkovskaia [24]
The perimeter of the square is calculated through the equation,
                                        4x = P
where P is the perimeter and x is the measure of the sides.

When P is 32 units then,
                                         32 units = 4(x)
                                                 x = 8 inches

This 8 inches is the diameter of the cylinder formed by the rotation. 
The circumference of the base is calculated through,
                            C = 2πr = πD
Substituting the known values,
                              C = π(8 units) = <em>8π units
</em>
<em></em>When π is equal to 3.14, we solve for the numerical value of the cylinder as follows,
<em>                                      C = 8(3.14) = 25.12 units
</em>
<em></em>Thus, the figure formed is a cylinder with base circumference equal to 25 units. The answer is the third choice. <em>
