Answer:
B represents a function.
Step-by-step explanation:
Recall these characteristics of a "function:"
Only one y-value can be associated with each x-value.
Thus, A could not represent a function because there are two points with x = 1 and two different y-values: (1, 1) and (1, -2).
B represents a function because for each input (x-value) there is one and only one y-value associated.
C not a function: (2, 3) and (2, -3) have two different y-values associated with one x-value (2).
D not a function: (-3, 4) and (-3, -4) (see A and C, above)
Answer:
y=1/2x(x) forms a "U" or "V" formation.
Step-by-step explanation:
Y is equal to 1/2 of x, times x it forms a sort of U.
Answer:
CACULATOR: shift solve= ---> x= π
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
A 180° rotation followed by a translation 1 unit down.
Explanation:
The points are mapped as follows:
J(3, 4)→J'(-3, -5)
K(3, 1)→K'(-3, -2)
L(1, 1)→L'(-1, -2)
A 180° rotation maps a point (x, y) to (-x, -y). This would map
J(3, 4)→(-3, -4)
K(3, 1)→(-3, -1)
L(1, 1)→(-1, -1)
The difference between these points and the image points are that each y-coordinate of the image is 1 lower than these. This means a translation 1 unit down would result in the image points.
Answer:
$140
Step-by-step explanation:
Orignal Price: $200
200 x 0.3
= 60
200 - 60
= 140
