Given that f(x) = 4x − 3 and g(x) = quantity of 2x minus 1, divided by 3, solve for g(f(2)).

First of all, we know that this problem is Function Composition Notation in form of f(g(x)), so here is the full answer:
f(x)=4x-3
g(x)=(2x-1)/3
Then,
f(x)=4x-3
f(2)=4(2)-3
f(2)=8-3
f(2)=5
In conclusion,
g(x)=(2x-1)/3
g(5)=(2×5-1)/3
g(5)=(10-1)/3
g(5)=9/3
g(5)=3. As a result, g(f(2))=3. Hope it help!

when x =2
then f(2)=4*2 - 3= 5
when x =f(2) =5
then g(5)=(2*5 -1)/3 = 9/3=3
then g(f(2))=3
