To find the inverse you have steps
1. replace f(x) with y
2. swich x and y places
3. solve for y
4. replace y with f⁻¹(x) (read 'f inverse')
so we have
f(x)=2x+1
replace f(x) with y
y=2x+1
switch x and y
x=2y+1
solve for y
x=2y+1
subtract 1
x-1=2y
divide both sides by 2

=y
y=

repplace y with f⁻¹(x)
f⁻¹(x)=
 
 
        
        
        
Answer:
736.05
Step-by-step explanation:699.00 x 5.3%=37.047
699.00 + 37.05 = 736.05
 
        
                    
             
        
        
        
(350x2=700) + (125x2=250) 700+250=950 so the perimeter is 950 meters long I hope this helps!
