Question

Choose the correct domain of the function in interval notation.

(-∞, ∞)
[-1, ∞)
(-∞, -1]
(-∞, 1]

Answer 1

The domain of a function is where the x of the function starts and finishes , but as that function doenst have an end or beginning, its domain is a) from negative infinity to infinity

Answer 2

domain : (-∞,∞)

Explanation:

Domain is the set of x values for which the function is defined

To find domain we check the x value for which the function is undefined

In the give graph , the graph is continuous and smooth.

There is no break in the graph.

We have graph for all values of x

So domain is set of all real values

domain : (-∞,∞)
