Use a graph to determine whether the given function is continuous on its domain. HINT [See Example 1.]
f(x) =
x + 7 if x < 0
2x − 5 if x ≥ 0
1
continuous discontinuous

If it is not continuous on its domain, list the points of discontinuity. (If there is no such point, enter NONE.)
x = 2

  2. In google type: "function graphs online"

    When you see list buf results click on:

    rechneronline.de/function-graphs/

    When page be open in blue rectacangle
    type: x+7

    in grey rectacangle click: 2*x-5

    In Display properties set:
    Range x-axis -20 to 20
    and
    Range y-axis -20 to 20

    Then click option Draw
