What is the difference between
f(g(x)) and f◦g??
f(x)=3x-5
g(x)=x^2-2x

I thought so, THANKS XD

To be precise, fog is the composite of f and g, that is, the function that, to each x, assigns the value f(g(x)). So, in precise language, fog and f(g(x)) are not the same. The first is the function, the second the value of the function of x.
You could use f(g) to represent such function, but fog is more usual.

f(g(x)) and fâ¦g are equivalent.
f(g(x)) = 3(x^2-2x)-5 = 3x^2-6x-5

f(g(x)) and fâ¦g are same if dot is not multiplication
fg (x) =(fog)(x)=f(g(x))
