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
