Write a user$-$defined function that fits data points to a power function of the form $y=b{x}^m.$ Name the function $[b,m]=$ power $f$ it $(x,y),$ where the input arguments $x$ and $y$ are vectors with the coordinates of the data points, and the output arguments $b$ and $m$ are the constants of the fitted exponential equation. Use powerfit to fit the data below. Make a plot that shows the data points and the function.
