Find f g x fx x 6 gx x6 2x12 12 2x6 2x12 2x Find fg x Fx

Find (f- g) (x). f(x) = x + 6, g(x) = x-6 2x-12 12 2x-6 2x+12 2x Find (fg) (x). F(x) = x^2, g(x) = 7x-6 7x^3 + 6x^2 7x^3-6x^2 7x^2 - 6x^3 7x^2 + 6c^3

Solution

22) f(x) = x+6 ; g(x) = x-6

( f- g)(x) = f(x) - g(x)

= x+6 - (x-6)

= 12

Option b

23) f(x) =x^2 ; g(x) = 7x -6

(fg)(x) = x^2(7x -6)

= 7x^3 - 6x^2

Option b
