Question
Use the real number line to find the range of values of x for which:
x < 0 and –3 ≤ x < 1
Solution
x < 0 and –3 ≤ x < 1
Both the given in equations are true in the range where their graphs on the real number lines overlap.
The graphs of the given in equations can be drawn as:
x < 0
–3 ≤ x < 1
From both graphs, it is clear that their common range is –3 ≤ x < 0
