Question

What is the range of the graph (5,3) (2,5) A) 3 < y < 5 B) 3 ≤ y ≤ 5 C) 2 < x < 5 D) 2 ≤ x ≤ 5

Answer 1

Answer:

B

Step-by-step explanation:

domain is the set of x-values

range is the set of y-values (corresponding to the x-values)

Now, since we want the range, we can immediately eliminate Choices C  &  D because they dealing with the DOMAIN ONLY (since x values).

Now, we have to choose from option A or option B.

The only difference is the greater than or less than sign with "equal to" signs as well. Whenever we are given 2 coordinate points, we can say that ALWAYS, we can graph a line segment using these 2 points. And line segments are all SOLID {meaning that the endpoints are INCLUDED).

What we mean by included is that the inequality sign should have "equal to" with it. Also, the two values of y-values are 3 and 5, thus range would be between 3 and 5 (inclusive). We can write:

Range = 3 ≤ y ≤ 5

Correct choice is B
