Inverse
replace f(x) wih y
solve for x
replace x with f⁻¹(x) and y with x
so
f(x)=3x+5/7
replace
y=3x+5/7
solve for x
minnus 5/7 both sides
y-5/7=3x
divide both sides by 3

=x
replace with f⁻¹(x)
f⁻¹(x)=
 
 
        
        
        
Group up the like terms and combine them
2x^2 and -7x^2 add up to -5x^2
6x and 2x add up to 8x
1 and -3 add up to -2
We end up with -5x^2 + 8x - 2
