I got this one wrong so obviously it will show me the correct one and it is =10x-30                                                 

Answer:

(f º g)(x) = f(g(x)) = 10(x-3)

Step-by-step explanation:

Given : [tex]f(x) = 10x[/tex] ,  [tex]g(x) = x-3[/tex]

To Find : (f º g)(x) = ?

Solution :

(f º g)(x) = f(g(x))

So,[tex]g(x) = x-3[/tex] and [tex]f(x) = 10x[/tex]

Substitute x = x −3 in f(x)

So, (f º g)(x) = f(g(x)) = 10(x-3)

Hence (f º g)(x) = f(g(x)) = 10(x-3)
