Find the domain and range of the following relations:
(-3,2) (-2,6) (-1,-2) (0,-2)

Domain: {-3,-2,-1,0}

Range: {2,6,-2}

Step-by-step explanation:

The number in front are domain, for example: (-3,2) -3 which is in front is the domain and 2 which is in the back is the range.

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.
