Answer 1

D grade....omg!!!

Answer 2

LOL^

Answer 3

f(x) o g(x) is like f(g(x)) right?

Answer 4

YES

Answer 5

its either d or c?

Answer 6

\(\Large \color{MidnightBlue}{\Rightarrow f(1 + x) }\)

\(\Large \color{MidnightBlue}{\Rightarrow 1 - (1 + x)+ (1 - x)^2 }\)

Answer 7

they want \[f(x)g(x)\] not the composition

Answer 8

I dont think in this question f(x)g(x) means f(g(x)).

It is a multiplication question and unfortunately, you got the wrong answer.

Answer 9

Oh so they want to multiply?

Answer 10

\(\Large \color{MidnightBlue}{\Rightarrow (1 - x + x^2)(1 + x) }\)

Answer 11

Yes its multiplication

Answer 12

@tiaph SEE THIS QUESTION IS WEIRD.

Answer 13

\(\Large \color{MidnightBlue}{\Rightarrow 1(1 - x + x^2) + x(1 - x + x^2) }\)

Answer 14

so its not c either? CAUSE I THOUGHT IF ITS NOT D IT WOULD BE C?

Answer 15

@Zarkon my pic is officially scarier than you :)

Answer 16

scarier ...maybe...definitely weirder though ;)

Answer 17

OOOOOOOOOOOOOOOO ITS B! :)

Answer 18

@ParthKohli YES URS FREAKS ME OUT!

Answer 19

It is not weird.

Im just gonna give the answer cause i assume you just want to double check your own answer.
(1-x+x^2)(1+x)
=1 + x -x -x^2 +x^2 + x^3
=1+x^3

Answer 20

\(\Large \color{MidnightBlue}{\Rightarrow 1 - x + x^2 + x -x^2 +x^3 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 1 + x^3 }\)

Answer 21
