The difference of course is the symbol between the f and g letters.
The circle notation means we're doing a function composition.
Writing is the same as saying where g is the inner function.
Here's an example
f(x) = x^2
g(x) = 3x
f( g(x) ) = ( g(x) )^2 ... note how x is replaced with g(x)
f( g(x) ) = ( 3x )^2
f( g(x) ) = 9x^2
-------------------
On the other hand, the dot notation means we multiply the f(x) and g(x) functions.
Going back to the previous example, we could say

Answer:
2nd option
Step-by-step explanation:
Answer:
b= -48
Step-by-step explanation:
by transposing,
43=59+b/3
b/3+59=43
b/3=43-59
b/3= -16
b= -16×3
b= -48
therefore the answer is b= -48
hope it helps!!!
