Nettet6. okt. 2024 · Figure 3.3. 7: Graph of a polynomial that shows the x-axis is the domain and the y-axis is the range. We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [ − 5, ∞). The vertical extent of the graph is all range values 5 and below, so the range is ( − ∞, 5].

NettetThe set { 1 } ⊂ R is closed, and the map f: R 2 R, ( x, y) ↦ x 2 + y 2 is continuous. Therefore the circle { ( x, y) ∈ R 2: x 2 + y 2 = 1 } = f − 1 ( { 1 }) is closed in R 2. Your set is also bounded, since, for example, it is contained within the ball of radius 2 centered at the origin of R 2 (in the standard topology of R 2 ).

This theorem allows us to calculate limits by “squeezing” a function, with a limit at a point a that is unknown, between two functions having a common known limit at a. Figure 2.27 illustrates this idea.
