Answer:
Step-by-step explanation:
f(x)=3x+15
let  f(x)=y
y=3x+15
flip x and y
x=3y+15
3y=x-15
y=1/3 x-5
or f^{-1}x=1/3 x-5
 
        
             
        
        
        
7 x 6= 42
7(6)= 42
 Re arrange it??
        
                    
             
        
        
        
tany =2x+C is the required differential equation.
