Some of the graphs are continuous graphs while some are discontinuous graphs
How to determine the domain, range and the function type?
Continuous graphs are graph that there is a y value for all x values
On the other hand, some graphs can be discontinuous graphs. This is so because there have holes or jumps or gaps on the coordinate plane
Also, the domain and the range of a relation are the set of input and output values of that relation, respectively
Using the above as a guide, we have:
Graph a
- Continuous? Yes
- Domain: -∝ < x < ∝
- Range: y >= 0
Graph b
- Continuous? No
- Domain: x < 2 and x > 2
- Range: y < 7 and y > 7
Graph c
- Continuous? Yes
- Domain: -∝ < x < ∝
- Range: y >= 1
Graph d
- Continuous? No
- Domain: -∝ < x < ∝
- Range: y <= 1 and y > 4
Graph e
- Continuous? No
- Domain: x < 3 and x > 3
- Range: -∝ < y < ∝
Graph f
- Continuous? No
- Domain: -∝ < x < ∝
- Range: y < 1 and y > 1
