Question

The graph of the function y=f(x)

Answer 1

Answer:

  [2, 5)

Step-by-step explanation:

The vertical extent of the function is its range. Here, that extent is from y=2 to y=5, except that y=5 is not included (indicated by the open circle on the graph). So, the range is ...

  2 ≤ y < 5

In interval notation, we use a square bracket when the end point is included, and a curved parenthesis when it is not.

  range: [2, 5)
