IN MATLAB:

Which of the following commands correctly adds the x-label \"time (s)\" to a plot? xaxis(\'time (s)\') xlabel[(\'time (s)\')] xlabel(\'time (s)\') xlabel(\"time (s)\") Graphically, the max/min of a function (F) is where the slope of a line tangent to the function equals zero. What Matlab command(s) would you use to do this? roots(F) polyder(F) roots(polyder(F)) polyder(roots(F))

Solution

C)
The correct option is 3 . xlabel(\'time (s)\')

Explanation :
The matlab command to set label for x-axis of the plot graph
using xlabel(\'labelMessage\')
where labelMessage is place where label of the x -axis of plot .

D.)
The correct option is 3 . roots(polyder(F))

Explanation :
Derivative of the function that is used to find the
slope of the tangent line and find its roots .
