Question

Graph the set (x-1 ≤x≤5) on the number line.

Then, write the set using interval notation.
(See picture attached)

Answer 1

Answer: -4 < 2 (X - 3) ≤ 4

Distribute the middle part

-4 < 2X - 6 ≤ 4

add 6 to all three sections

2 < 2X ≤ 10

Divide all sections by 2

1 < X ≤ 5

----------------------------

Graphing: put an open circle on 1 and draw

a line to the right

put a solid circle on 5 and draw

a line to the left

These two lines should meet and stop
