Answer:

Theo công thức: \(y=f\left(x\right)=2x-3\)

Với \(f\left(x\right)=\frac{1}{4}\)

\(\Rightarrow2x-3=\frac{1}{4}\)

\(\Rightarrow2x=\frac{13}{4}\)

\(\Rightarrow x=\frac{13}{8}\)

Với \(f\left(x\right)=\frac{-3}{2}\)

\(\Rightarrow2x-3=\frac{-3}{2}\)

\(\Rightarrow2x=\frac{3}{2}\)

\(\Rightarrow x=\frac{3}{4}\)

Với \(f\left(x\right)=2005\)

\(\Rightarrow2x-3=2005\)

\(\Rightarrow2x=2008\)

\(\Rightarrow x=1004\)
