2d graph for Maple compatibility : plot

plot(f(x),x) draws the graph of y = f (x). The second argument may specify the range of values x=xmin..xmax. One can also plot a function instead of an expression using the syntax plot(f,xmin..xmax). plot accepts an optional argument to specify the step used in x for the discretisation with xstep= or the number of points of the discretization with nstep=.
Input :
plot(x^2-2,x)
Output :
the graph of y=x^2-2
Input :
plot(x^2-2,xstep=1)
or
plot(x^2-2,x,xstep=1)
Output :
a polygonal line which is a bad representation of y=x^2-2
Input!
plot(x^2-2,x=-2..3,nstep=30)
