Y = 8 - 2- x^2

0 = 8 – 2 – x^2

(-x – 4)(x – 2)

- x – 4 = 0 and x – 2 = 0

-x = 4 x = 2

X = - 4

Do I do this?

Y = 8 -2x -x^2

= 8x - (2x^2)/2 - x^3/3

= 8 - x^2 - x^3/3

= [8x - x^2 - x^3/3] – [8x - x^2 - x^3/3]

= [(8x 2) - 2^2 - 2^3/3] – [(8 x -4) - 〖-4〗^2 - 〖-4〗^3/3]

= [16 – 4 + 8/3] – [-32 + 16 - 64/3]

= 141/3 – [-16 - 311/3]

= 141/3 – [-16 + 211/3]

= 141/3 - 5 1/3
