Which of the following describes a one-to-one function?
Answers
Option C) is correct.
Step-by-step explanation:
One to one function can be checked by using horizontal line test and vertical line test.
A)
the graph of this function ia attached below named as Graph 1.
The above function did not pass the horizontal line test therefore it is not a one to one function.
the graph of this function is attached below named as Graph 2.
The above function did not pass the vertical line test therefore it is not a one to one function.
the graph of this function is attached below named as Graph 3.
The above function pass the horizontal line test as well as vertical line test and therefore this function is one to one function.
the graph of this function ia attached below named as Graph 4.
The above function is a floor function and fail the vertical line test.
Therefore, correct answer is option C).
For more information, refer the link given below
check the picture below.
bearing in mind that a one-to-one function must pass the horizontal line test as well as the vertical line test.
now, |x| is the graph of a letter V more or less, and that'd fail the horizontal line test.
the first piecewise function, has say 4 : x < 0, namely for all values before 0, "y" is a steady constant of 4, that will be a horizontal line and will definitely fail the vertical line test.
[[x]] is pretty much the "floor function", and you can do a quick google search on it, or do it in your calculator, it should have a floor function, but that one will definitely fail the vertical line test as well.

The fraction 7/9 is greaterthan 0.7.
We have,
Given decimals and fractions.
0.7 and 7/9
Now,
0.7
This can be written as a fraction.
= 07/10
= 7/10
Multiply 9/9 to make the fractions the same.
= 63/90
And,
7/9
Multiply 10/10 to make the fractions the same.
= 70/90
Comparing the fractions 63/90 and 70/90.
63/90 < 70/90
This means,
0.7 < 7/9
Thus,
The fraction 7/9 is greaterthan 0.7.

Answer: 7/9
Explanation:
In order to compare the two numbers, we can write both as a fraction.
7/9 is already written as a fraction. The other number instead can be written as
We see that this number is smaller than , because it has a greater denominator (and same numberator), so we can conclude that 7/9 is greater than 0.7.

Answer:
Total amount Tiffany has to pay = $276.66
Step-by-step explanation:
Cost of one pair of jeans = $42
Cost of three pairs = 3(42) = 126
Cost of one shirt = 27
Cost of five shirts = 5(27) = 135
Total amount Tiffany has to pay = 126 + 135 = 261.
Sales tax = 6%
6% of 261 = 0.06(261) = 15.66
So, total amount including sales tax Tiffany has to pay = 261 + 15.66 = 276.66.

25 + (12 * 10 + -1x * 10) = 5(2x + -7)
25 + (120 + -10x) = 5(2x + -7)
Combine like terms: 25 + 120 = 145145 + -10x = 5(2x + -7)
Reorder the terms:
145 + -10x = 5(-7 + 2x)
145 + -10x = (-7 * 5 + 2x * 5)
145 + -10x = (-35 + 10x)
Solving145 + -10x = -35 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
145 + -10x + -10x = -35 + 10x + -10x
Combine like terms: -10x + -10x = -20x145 + -20x = -35 + 10x + -10x
Combine like terms: 10x + -10x = 0145 + -20x = -35 + 0145 + -20x = -35
Add '-145' to each side of the equation.145 + -145 + -20x = -35 + -145
Combine like terms: 145 + -145 = 00 + -20x = -35 + -145-20x = -35 + -145
Combine like terms: -35 + -145 = -180-20x = -180
Divide each side by '-20'.
x = 9
Simplifyingx = 9.
