The expression is [tex]f (x) = \frac{x}{3} - 6[/tex]
Step-by-step explanation:
Step(i):-
Given variable start with 'x'
The variable 'x' is divided by '3' so [tex]\frac{x}{3}[/tex]
Step(ii):-
The variable 'x' is divided by '3' so [tex]\frac{x}{3}[/tex] and after that subtract '6'
Then the expression
