Answer:
(
h
∘
f
∘
g
)
(
x
)
 is known as a composite function. Here's how composite functions work:
let's say that  
x
=
1
. Your function  
g
(
x
)
=
1
3
(
x
)
 now produces a  
y
 output of  
1
3
 , since  
g
(
1
)
=
1
3
(
1
)
. Within a composite function, the y-value of one function becomes the x-value of the next, like so:
g
(
1
)
=
1
3
⇒
f
(
1
3
)
=
17
3
⇒
h
(
17
3
)
=
17
Therefore,
(
h
∘
f
∘
g
)
(
1
)
=
17
Based on this, to find the function for  
(
h
∘
f
∘
g
)
(
x
)
 (combined from right to left, by the way), simply replace  
x
 in  
f
(
x
)
 with the function  
g
(
x
)
, and replace  
x
 in  
h
(
x
)
 with the function of  
(
f
∘
g
)
(
x
)
, to get  
(
h
∘
f
∘
g
)
(
x
)
.
This, simplified, is equal to  
2
x
+
15
, and therefore  
(
h
∘
f
∘
g
)
(
1
)
=
2
(
1
)
+
15
=
17
Hope that helps!
