Pineapples are on sale for $2 each, but customers can buy no more than 5 at
this price.
for pineapples bought at the sale price, the total cost, y, is directly
proportional to the number bought, x. this function can be modeled by y = 2x.
what is the domain of the function in this situation?

b is the answer that makes most sense

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.

the answer would be c:   ax + b = ax + c
