In interval notation, x should be described as: (-infinity, 12]
which says that x could be any value less than and equal to 12.
To graph you would draw a number line then mark the value for 12 with a closed loop and shade all of the line to the left of the 12 and the shading continues in an arrow to the left to show that it never ends.
your graph will look similar to this.
FYI - The | are the hash marks for your numbers on the line and the double bar === is your shaded area. The periods are just for spacing purposes. The @ symbol marks your closed loop, on your paper it should be a filled circle on the line.

Hope this helps
x ⤠12
To graph, make a horizontal line with a closed circle at 12 and extending toward infinity to the left.
"not larger" is the same as "less than or equal to".
