Which graph represents an odd function?Answer by using: A, B, C, or D for each graph.
2 answers:
Answer: Option C is the correct graph.
Explanation:
An odd function satisfies the condition,
This indicates that for any point (x,y) on the graph, the point (-x,-y) will also be present.
Why Option C is correct:
Option C includes the point (1,2), which implies the point (-1,-2) must be present.
Indeed, (-1,-2) is among the points.
Other pairs like (2,3) with (-2,-3), (3,-1) with (-3,1), and (4,0) with (-4,0) are also found. Hence, the function represented is odd.
Why other options are incorrect:
In Option A, (1,3) is given, so at x = -1, y should be -3, but instead y = 1, so it’s not odd.
Option B has (1,0), so at x = -1, y should be 0, but y = -3, so it is not odd.
Option D features (1,-1), meaning at x = -1 y should be 1; however, y = -1, so it's not odd.
The graph displayed in the third position corresponds to an odd function. Choice (C) is correct.
Additional details:
An inverse function reverses the input-output pairs of another function: for f giving y from x, the inverse provides x from y.
The relation links inputs (domain) with outputs (range).
Definition: A function is odd if
If the points meet and
,
Then the points in graph (C): and
have pairs of the form
and
. This confirms the graph depicts an odd function.
Therefore, the third graph corresponds to an odd function. Option (C) is correct.

Step-by-step explanation:
Notation
is the sample mean
indicates the population mean (the variable of interest)
s signifies the sample standard deviation
n denotes the sample size
Solution to the problem
The mean's confidence interval is derived from the following formula:
(1)
In this instance, the 9% confidence interval corresponds to:
We can determine the mean using the following:
Additionally, the margin of error can be calculated as:
The margin of error for this situation is expressed as:
Next, we find the standard error:
The critical value for a 95% confidence interval using a normal standard distribution is roughly 1.96, and substituting gives us:
For the 98% confidence interval, the significance corresponds to and
with a critical value of 2.326, yielding a confidence interval of:
Response:
If there are "p" pounds of peanuts and "m" pounds of a mixture containing '20% peanuts and 80% almonds', then we can formulate the following equations:
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
The solution yields 5 lb peanuts and 5 lb mixture.
Detailed explanation:
In the mixture that Delaney desires to create, there will be
lb
= 6 lb of peanuts
Thus, there will be (10 - 6) lb
= 4 lb of almonds
If Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then based on the problem statement,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
From equation (2), we derive
m = 5 --------------(3)
From (1) and (3), we find that
p = (10 - 5) = 5
To start, we will shift the non-repeating segment of the decimal to the left side by dividing by a power of 10.
Then we will assign a variable to represent the value and also shift the repeating segment to the left.
Essentially, the concept here is that we can denote the repeating portion with a variable, let's say "x", and move forward with the calculation;
you can verify that using your calculator.
