Need with the composition of functions. i have attached a screenshot of the question.

using (f ○ g)(x) = f(g(x))

substitute x = into f(x)

f( ) = 4 / ( - 3 ) ×

=

The denominator of f(g(x)) cannot be zero as this would make f(g(x)) undefined. Equating the denominator to zero and solving gives the value that x cannot be

solve 7 - 3x = 0 ⇒ x =

domain : x ∈ ( - ∞, ) ∪ ( , + ∞ )

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:
