graph{x^2+4 [-5, 5, 0, 10]}
Explanation:
choose a few arbitrary value for x and solve the equation and put points in (x,y) format in cartesian coordinates. Then combine them.
give x=0 to find at which point graph intercepts y axis,
if exists, try to find roots of the equation in order to get at which point(s) graph intercepts x axis. Note that graph may not intercept x axis...
Suppose that your equation is
to find if it intercepts x axis, calculate
if
