Matlab Question 567809load flow_rate.datflow_rateCommand WindowFlow_rate=08002980411406132081400101490121440141180161100 A river's water flow rate is measured every 2 hours. The flow rate has been recorded and stored in afile called "flow_rate.dat".Download the file "flow rate.dat", (i.e. right click and select "Save link as..") and save it underyour current working directory in MATLAB. Reading data from a file in MATLAB is accomplishedusing the load function. In the "Command Window" or in your script file, type:>> load flow_rate.datThere are 2 rows in "flow_rate.dat". The first row represents the # of hours and the second rowrepresents the data for the flow rate of the river in cubic feet per second. The above commend wouldread the data from the file and store the result in a matrix variable called "flow_rate". Hence, in the"Command Window", type:>> flow_rateThis will display the both columns of data in the matrix "flow_rate".Write a script that will fit a cubic function to the data and create a plot with 100 points for the fittedfunction. Also, plot the original data as "black circles" on the same graph. The title for the plotshould include the degree of the fitted polynomial. Include appropriate x and y labels for the plot.Suppose the water's flow rate eventually drops to zero. Use the best-fitted function to predict andprint out the # of hours it takes the water's flow rate to drop to zero.

Step 1: Load the file flow_rate.dat. It will be stored in the form of a matrix with two rows. Step…
