Question 906092
If there is a *[Tex \Large \le] sign in the original inequality, then the answer is indeed *[Tex \Large x \le 4]


However, if there is NO underline under the inequality sign, and you have a *[Tex \Large <] sign only, then the answer is *[Tex \Large x < 4]

Graphing


Step 1) Draw a number line. Be sure to include x = 4 on the number line


Step 2) If the answer is *[Tex \Large x \le 4] plot a closed circle at x = 4. If the answer is *[Tex \Large x < 4] plot an open circle at x = 4.  


Step 3) we have a "less than" as part of the answer, so we shade to the left of the circle (whether it's open or closed)
