Part B How did you do on the question about key features of functions? If you found it challenging, try to
pinpoint a reason it might have challenged you and list any concepts or methods you should review from
Algebra 1.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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.

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question
