Maths How To Draw This Line?

Bro you know what you can copy and paste the equation in google and hit enter. Only the equation.

If you are keen on plotting then i suggest use Matlab or Excel .


All the best.

Maths How To Draw This Line?

For a start,this equation does not represent a line - it represents a curve.
I have to admit I'm puzzled - how can you have been asked to draw the curve when you appear not to what y = e^x looks like ? If you do know what it looks like, treat this as two separate graphs : y1 = e^x, and y2 = -x; select several x-coordinates, mark them on your sketch, and add their y-coordinates to get several points on a new curve y = y1 + y2 i.e. y= e^x - x.
If you haven't heard of y = e^x, then I don't think I could explain on "Answers" how to draw the graph.
