See below.

Explanation:

#x>=3#

First consider #x=3#

This is the vertical line through the point (3, 0) and all other values of #y in RR#

Hence, #x>=3# is the area consisting of this vertical line and points #(x,y): x>3 forall y in RR#

This area is shown graphically by the shaded area below extended to #+oo# for #x# and #(-oo, +oo)# for #y#

graph{x>=3 [-4.45, 8.04, -2.97, 3.275]}
