4

0

1

Answer 1

you have to find f[g(2)]
first solve g(2), by plugging 2 on function g(x) for the value of x

Answer 2

ok then

Answer 3

what do you get ?

Answer 4

4

Answer 5

let see f(x) = 2x-4 let substitute the x for 2
2(2) - 4
4 - 4 = 0

Answer 6

since you have that g(2) = 0 now substitute the 0 for the x on function f(x)

Answer 7

-4

Answer 8

let see f(x)= 3x +1 substitute the 0 for the x
3(0) +1 = ???

Answer 9

o i was doin 2(0)-4

Answer 10

that is function g(x),

Answer 11

o so its 1
