Question

Find the inverse of f(x)=4x+3

Answer 1

The correct answer is actually
`f^-1(x)=(1)/(4) x-(3)/(4)`

Answer 2

`f(x) = 4x+3\\\\\text{Write f(x) as y = 4x+3}\\\\\text{Replace x with y,}\\\\x =4y +3\\\\\text{Solve for y:}\\\\ \implies x =4y+3\\\\\implies 4y = x-3 \\\\\implies y =\frac{x-3}4\\\\\implies f^(-1) (x) = \frac{x-3}4\\\\\text{This is the inverse of f(x)}`
