The correct answer for part A is 5x² +7x -4. 5x³ -x² -8x -7 is the right answer for part B. Polynomials are always closed if under addition or subtraction. The answers of both parts A and B are polynomials.

Hope this helps!

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

= 26 - 4

= 22

For x = 2,

y = 26 - 4(2)

= 26 - 8

= 18

For x = 3,

y = 26 - 4(3)

= 26 - 12

= 14

For x = 6,

y = 26 - 4(6)

= 26 - 24

= 2

Therefore, table for the function will be,

x y

1 22

2 18
