this may help uh to solve this type of problems.
Ответ:
Let f(x)= 2x+3 and g(x)= 1/2x -3/2. Evaluate (fog)(-3)
First solve for g(x) by replacing x with -3:
g(x) = 1/2(-3) -3/2
g(x) = -3/2 - 3/2
g(x) = -3
Now solve for f(x) by replacing x with -3:
f(x) = 2(-3) + 3
f(x) = -6 +3
f(x) = -3
The answer is -3
