Suppose we want to choose a value of x within 3 units of 12. [This means a value of x that is less than or equal to 3 units away from 12.]
a. Think about some values of x that meet this constraint.
b. Write an inequality that represents all values of x that meet this constraint.
c. On the number line below, represent all values of x that meet this constraint.

Draw:
Box 1: Enter your answer using inequality notation. Example: 3<=x<4
Use "or" to combine intervals. Example: x<2 or x>=3
Enter all real numbers for solutions of that type
Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4)
Enter "DNE" for an empty set. Use "oo" to enter Infinity.
Box 2: Enter your answer by drawing on the graph.
