Interpret the following graph in detail Domain and Range graph i Identify the domain and range ii Does this graph represent a function and a oneone function Why class=


Answer :

Answer:

Step-by-step explanation:

The domain is -infinity < x < infinity    (or all real x)

The range is  -infinity < f(x) < infinity

The graph does represent a function as it passes the vertical line test

- this means we can draw a vertical line through any point on the graph which only passes through the graph at one point.

If the first turning point of the graph does not contain a horizontal line it is also one-to-one. It's hard to tell from the graph but a strongly suspect there is no horizontal line.
