Domain is x values and range is y values.  For this one, you can see for the x values, it stops at zero.  The domain would be x is greater than or equal to zero because it doesn't go past 0.  For the range you are looking at the y values.  Again it stops at zero.  There are no y values greater than zero.  So the only possible answer is C.

Step-by-step explanation:

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.
