Question

What is the domain of the relation below?

Answer 1

Answer:

it should be all real number

Step-by-step explanation:

Answer 2

Answer:

A. x ≤ 5

Step-by-step explanation:

We know that finding the domain consists of finding where the function has an x value, so that rules out answer choice B which uses y, that gives the range.

Since the graph cuts off at a point (x = 5), We can confer that the domain is not all real numbers, so that eliminates D.

Now when you look at the graph, you can see that at x = 5, the x values start becoming smaller, so that rules out answer choice C which states that the x values at 5 start to get larger.

The answer is A because it includes x = 5, and the x values of the graph progressively get smaller.
