Find the coordinates of a relative minimum of a function.

Operation

The function must be in Y1 in the list.

Draw a graph of the function and trace to a point near a minimum point.

Activate the program, which will give the coordinates of the minimum point, correct to three decimal places.

Test the program by finding the relative minimum of the function

y = x2 x – 1.

The result is (0.500,-1.250).
