I have a function y=f(x) where 'x' varies within a particular range. For some values of 'x', 'y' gives positive values whereas for some other values 'y' gives negative values. I have two questions:
1.. I have written a table as;
How can I get a table for only the positive values of 'y' and their corresponding 'x' values?
2.. Using the plot command (without using the table), how can I get a plot for only the positive values of 'y' and their corresponding 'x' values?
