Question

Find the domain of the graphed function.​

Answer 1

Domain = {
`x \leq 0` }

Explanation:

The domain of a function is the set of x values for which the function is defined for.

When given a graph, we look at the graph and see from which x value to which x value the graph is defined for.

The left side of the graph goes on an on to the left, towards NEGATIVE INFINITY.

The right side, though, is stopped at x = 0 and doesn't go anywhere to its right.

So, the function is defined for x = -∞ to x = 0

Or we can say any value of x less than or equal to 0. We can write:

Domain = {
`x \leq 0` }
