Hey!
-------------------------------------------------
In a function <u>ONE input-value can be assigned to only ONE output-value.</u>
We can use the <u>vertical line test</u> to see whether each graph is a function or not.
-------------------------------------------------
Graph 1, 5, and 6 are functions. When we draw a line vertically we can see that the line only passes through 1 point on the graph.
Graph 2, 3, and 4 are NOT functions. When we draw a line vertically we can see that the line passes through more then 1 point on the graph.

Hello from MrBillDoesMath!
Answer:
Choice B
Discussion:
The answer shown highlighted is the correct answer
For a function, each value in the domain should be assigned a unique value in the range. In the case of ordered pairs, each x value in an order pair should have a unique y value. This aspect fails for Choices A, C, and D. Details follow.
Choice A: Not a function because (3,3), and (3,2) both have x = 3 but associated y value is not unique (equal 3 or 2)
Choice C: Not a function because (1,-1) and (1, -2) both have x = 1 but associated y value is not unique (equals -1 or -2)
Choice D: Not a function because (2,3) and (2,1) both have x= 2 but associated y value is not unique (equals 3 or 1)
Choice B has no such issues as an x value is repeated.
Thank you,
MrB
Answer:
D. w < 3.3
Step-by-step explanation:
It cannot be A because a book is 2.3 pounds. (w > 2.3) it would be correct if it was (w ≥ 2.3)
It cannot be B because majority of the books has a greater mass than 2.4 pounds. (w < 2.4)
It cannot be C because all books have a lesser mass(or equal mass) than 3.2 pounds (w > 3.2)
It is D because W is less than 3.3 pounds ( w < 3.3)
