Given: f(x) = 3x + 2 and g(x) = 2x - 4

Answer:
ƒ(g(x)) = 6x^2-12x+2
Step-by-step explanation:
ƒ(x)=3x+2
g(x)=2x-4
ƒ(2x-4)= 3x(2x-4)+2
ƒ(2x-4)=6x^2-12x+2
ƒ(2x-4)=6x^2-12x+2
In f(x) = 3x + 2, the x is being represented in the function. So, if we replace the x with the g(x) functions, we get:
f(g(x)) = 3(2x - 4) + 2
f(g(x)) = 6x - 12 + 2
f(g(x)) = 6x - 10

1 tub of popcorn = t
1 drink = t - 3.5
4(t - 3.5) + 2t = $32.50
4t - 14 + 2t = 32.5
6t = 32.5 + 14
6t = 46.5
t = 46.5 / 6
t = $7.75
