Problem 5

Answers:Domain = $-3 \le x \le 3$ which in interval notation is [-3, 3]Range = $-3 \le y \le 3$ which is also [-3, 3] in interval notationIs it a function? Yes

-----------------

Explanation:

The domain is the set of allowed x values. Here we see that x = -3 is the smallest possible x value and x = 3 is the largest. So x is anything between -3 and 3, including both endpoints. We write $-3 \le x \le 3$ to indicate this. That converts to [-3,3] in interval notation. The square brackets mean "include this endpoint".

The range is the same story, but with the y values. Coincidentally, the range has the same exact endpoints as the domain does. This won't always be the case.

This graph is a function because it is not possible to draw a single vertical line through more than one point on the relation curve. Any x value pairs with one and only one y value. The next problem is a different story.

==========================================================

Problem 6

Answers:Domain = $-4 \le x \le 4$ which in interval notation is [-4, 4]Range = $-3 \le y \le 3$ and that is [-3,3] in interval notationIs it a function? No

----------------------------

Explanation:

We use the same idea as before. The left most point tells us the smallest x value, and the right most point tells us the largest x value. The domain is everything in this interval including both endpoints. The range is a similar story but we're looking for the lowest and highest points to get the smallest and largest y values respectively.

This relation is not a function because this graph fails the vertical line test. It is possible to pass a single straight vertical line through more than one point on this curve. For example, draw a vertical line through x = 2 and it crosses the circle twice. This means the input x = 2 leads to more than one output, but a function must have exactly one output for any valid domain input value.

Answer from: Quest

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
