Verified answer

f(g(9)) i guess it what you're trying to see

g(9)

-2(9)-1

-18-1=-19

f(-19)=-19-2=-21

O.D. I'm not sure of your quetion; however, if you are seeking the results of multiplying the 2 functions and then multiplying the results by 9, I would first multiply (X-2) x (-2x -1)

Multiplying all the second by the first of the first one gets( -2X^2-X) and multiplying all of the second by the second of the first one gets (+4X+2) and adding both togather one gets( -2X^2 +3X + 2) Multiplying this by 9 one gets: (-18X^2 + 27X + 18)

(f*g)x = (x-2)(-2x-1)

(f*g)(9) =(9-2)(-18-1)

=7*(-19)

= -133 ......Ans

(f.g)(9)= f(9)*g(9)

= (9-2)(-2*9 -1)

= 7(-19)

= -133

I think it's 54

Because f = -2

and g = -3
