Question

find the inverse of the function
f(x)=2x+4​

Answer 1

Answer:

Replace f(x)fx with yy. y=2x−4y=2x-4Interchange the variables. x=2y−4x=2y-4Solve for yy. Tap for more steps...y=2+x2y=2+x2Solve for yy and replace with f−1(x)f-1x

Answer 2

Answer:

solution, f(x)=2x+4

let y=f(x)

y=2x+4

y-4=2x

1/2(y-4)=x

1/2(y-4)=f^-1(y)

therefore, f^-1(x)=1/2(x-4)
