Answer:

domain : (-∞,∞)

Step-by-step 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 : (-∞,∞)

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:

$\dfrac{x^2}{4}+\dfrac{y^2}{16}=1$

Step-by-step explanation:

If the ellipse has its x-intercepts at points (2, 0) and (-2, 0) and y-intercepts at points (0, 4) and (0, -4), then its symmetric across the y-axis and across the x-axis.

Moreover,
