Answer:
The answer is below
Step-by-step explanation:
A composite function is a function which is placed inside another function, this type of function can be calculated by substituting one function into another function.
If two functions g(x) and f(x) are inverses, then each will reverse the effect of the other. That is, (f○g)(x)=f(g(x))=x and (g○f)(x)=g(f(x))=x.
Given that F(x) =(x+4)/3 and g(x) = 3x – 4
a) (f o g)(x) = f[g(x)]
= f(3x - 4)
= [(3x - 4) + 4]/3
= [3x - 4 + 4]/3
= 3x / 3
= 3
b) (g o f)(x) = g[f(x)]
= g[(x + 4)/3]
= 3(x + 4)/3 - 4
= x + 4 - 4
= x
We can see that (f o g)(x) = (g o f)(x) = x. Hence the functions are inverse functions.
The number is 78 and you can say The answer is 78 because if you multiply 26 * 3 it equals 78 and if you check 6 goes into the number
