Answer:
1.a. not a function
1.b. function
1.c. function
1.d. not a function
1.e. not a function
1.f. not a function
Step-by-step explanation:
1.a.
The arrows from x to y show that the ordered pairs of this function are:
(1, 4), (1, 5), (0, 7), (1, 6), (2, 5).
Since the x-coordinate 1 is used in two different ordered pairs, (1, 4) and (1, 5), this relation is not a function.
1.b.
Each x-coordinate is used only once, so this relation is a function.
1.c.
All x-coordinates are different. Function.
1.d.
Two ordered pairs have the same x-coordinate. Not a function.
1.e.
Two ordered pairs have the same x-coordinate. Not a function.
1.f.
Two ordered pairs have the same x-coordinate. It does not pass the vertical line test. Not a function.

Answer: <em><u>1/9, 0.48, 0.6, 2/3, 5/6</u></em>
Step-by-step explanation:
Order these numbers: 0.6 , 2/3 , 5/6 , 1/9 , 0.48
0.6 = 0.6
2/3 = 0.6666666....
5/6 = 0.8333333....
1/9 = 0.111111.....
0.48 = 0.48
In order, it will go 1/9, 0.48, 0.6, 2/3, 5/6

Answer:
y = (x-1/x+2)(x-1)
y = -3(x-1)
y = -3x+3
-3x y = 3
x y = -1
x(0) y = -1
y = -1
