Practice problem
Select the intervals on which this graph is continuous.
(−∞,−12)(-\infty,-\frac12)(−∞,−21)
(−∞,−3](-\infty,-3](−∞,−3]
(−3,−1)(-3,-1)(−3,−1)
[4,∞)[4,\infty)[4,∞)
[−12,4][-\frac12,4][−21,4]
[−1,∞)[-1,\infty)[−1,∞)
(−1,∞)(-1,\infty)(−1,∞)
Type a concept, like “slope” or “photosynthesis”.
