Answer:
In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
Step-by-step explanation:
Requirement to be a function:
For a relationship to be a function, all values of x must have only one corresponding value of y.
In this question:
For x = -7, y = 2
For x = -1, y = 0
For x = 4, y = 0
For x = k, y = 0
A value of x must not have more than 1 value of y.
In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
Answer:
A. 60°
Step-by-step explanation:
3tan^3 x= tan x
3tan^2x = 1
tan^2 x = 1/3
tan x = 1/
x = 60°

Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0,
11111nata11111 [884]
Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}
Step-by-step explanation:
For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.
Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.
Rectangle=4 sides
Perimeter=add all sides
