I have to understand this to understand my homework. What is the difference between these two function compositions?
f at g(a)
f o g at a
The Attempt at a Solution
Let's make f(a) = a^2 and g(a) = 3a.
It seems that "f at g(a)" means f(g(a)) which equals (3a)^2.
And it also seems like "f o g at a" means f(g(a)) which equals (3a)^2.
