What is the range of the function y = 3x – 2 if the domain is {0, 1, 2}? A {–2, 0, 3}
A , {–2, 0, 3}

B {–2, 1, 4}
B , {–2, 1, 4}

C {0, 1, 2}
C , {0, 1, 2}

D {1, 2, 4}

what's that

we need the options

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.
