Neil started a stamp collection with 12 stamps. every week, he adds 4 more stamps to the collection. which function f represents the relationship between the number of stamps (s) and the number of weeks (w)? a. s = f(w) = 12 + 4w

b. w = f(s) = 12s + 4

c. s = f(w) = 12 + 4s

d. w = f(s) = 12w + s

e. s = f(w) = s – 12

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.
