Use a graph to determine whether the given function is continuous on its domain. HINT [See Example 1.]
x + 7 if x < 0
2x − 5 if x ≥ 0
If it is not continuous on its domain, list the points of discontinuity. (If there is no such point, enter NONE.)
x = 2
This is very simple and quick to graph.
Have you tried to graph these?
What don't you understand?
In google type: "function graphs online"
When you see list buf results click on:
When page be open in blue rectacangle
in grey rectacangle click: 2*x-5
In Display properties set:
Range x-axis -20 to 20
Range y-axis -20 to 20
Then click option Draw
