F(x)=4x+m
y=4x+m
y-m=4
y-m/4=x
f^-1(x)=x-m/4
compare the two inverse equations
nx+3/4=x-m/4
nx+3/4=x*1/4-m/4
n=1/4
3/4=-m/4
m=-3

F(x) =4x+m
  x  = 4y+m
x-m=4y
x-m  = y
  4
f⁻¹(x) = x-m
             4
pastu bandingkan 
f⁻¹(x) = x-m
             4
f⁻¹(x) = nx + 3
                    4

m=3

pastu cari jawapan n

=  nx
4
x = 4 nx
x/x = 4n
1/4 = n
