Question

If f(x) = -1/2x -3 find f^1(x)

Answer 1

f^1(x)=f(x), do you want an inverse instead?

Answer 2

Lib \[f^1(x)=f(x)= \frac{-1}{2x-3}\]

Answer 3

for this one i am going to guess that you have
\[f(x)=-\frac{1}{2}x-3\]

Answer 4

which means the inverse we find by writing
\[x=-\frac{1}{2}y-3\] and solve for y
\[x+3=-\frac{1}{2}y\]
\[-2x-6=y\]
\[f^{-1}(x)=-2x-6\]
