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.
b. m = 0
c. m = 10
d. m = 1
Answer:
option d
Step-by-step explanation:
y= x+10
1 is the coefficient of x value, so 1 is the slope
Answer:
Step-by-step explanation:
Given expression:
Consider the numerator and the denominator separately.
Numerator:
Denominator:
The whole expression:
Of the 200 packages of bagels sold, 15 of them are sesame seed bagels. What percent of the bagel packages sold are sesame seed bagels?
The fraction represents the number of sesame seed bagel packages out of all the packages.
To find out what percent are sesame seed bagel packages, we can turn the fraction into a percent.
We can first reduce the fraction by dividing both the numerator and denominator by the Greatest Common Factor of 15 and 200 using 5.
15 ÷ 5 = 3
200 ÷ 5 = 40
3 ÷ 40 = 0.075
0.075 × 100 = 7.5%
Therefore, 7.5% of the bagel packages sold were sesame seed bagels.
A long rectangle divided along the length into 4 equal squares is shown. Along the upper edge length of the second square is shown another square, and along the lower edge length of the fourth square is shown another square. The first square from the left has two adjacent sides labeled as 3 inches each.
