Plis tell me if it’s correct and do I need to divide by 2 at the end like I did?

yes you did it correctly

Step-by-step explanation:

id say you did you put alot of hard work into it even if u didnt get the answer

yes

Step-by-step explanation:

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
