Here's a simple example of an interpolation function that seems to me to have gone awry. Maybe someone would be so kind as to tell my what's going on with this?

tst2 = {{0, 0}, MatrixForm[tst2]{0.0057269`, 0.2`}, {0.0366617`, 0.4`}, {0.158682`, 
    fx0.6`}, ={0.50688`, Interpolation[tst2];
0.8`}, {0.938627`, 1.`}};

MatrixForm[tst2]
fx = Interpolation[tst2];
Plot[fx[x], {x, 0.0, 0.9}]

Here's the result. The plot is of fx[x]

tst=

\begin{array}{cc} 0 & 0 \\ 0.0057269 & 0.2 \\ 0.0366617 & 0.4 \\ 0.158682 & 0.6 \\ 0.50688 & 0.8 \\ 0.938627 & 1. \\ \end{array}
