If(x)=4x+2 and g(x)=2x-4 what is f(g(x))

f(g(x)) = 8x-14

Step-by-step explanation:

You need to bring one inside the other so:

f(g(x)) = 4(2x-4) +2

f(g(x)) = 8x - 16 + 2 = 8x -14

instead of x in the f(x) function, you replace it with the function g(x)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
