Answer: Option C is the correct graph.

Explanation:

An odd function satisfies the condition,

$f(-x)=-f(x)$

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.

$f(1)=2$

Indeed, (-1,-2) is among the points.

$f(-1)=-f(1)=-2$

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 $f\left( { - x} \right) = - f\left( x \right).$

If the points meet $\left( {x,y} \right)$ and $\left( {- x,- y} \right).$ ,

Then the points in graph (C): $\left( {2,3} \right), \left( {-2,-3} \right), \left( {3, - 1} \right), \left( { - 3,1} \right), \left( {4,0} \right), \left( { - 4,0} \right)$ and $\left( {1,2} \right).$ have pairs of the form $\left( {x,y} \right)$ and $\left( {- x,- y} \right)$ . This confirms the graph depicts an odd function.

Therefore, the third graph corresponds to an odd function. Option (C) is correct.

The bus routes in a city run on average every 15 minutes. The route times can vary by three minutes. Which absolute value equati

AnnZ [3877]

Response:

$Max = 18\ mins$

$Min = 12\ mins$

Step-by-step explanation:

Information given:

$Time = 15\ mins$

$Variation = 3\ mins$

Objective:

Calculate the maximum and minimum values

The max value is found as follows:

$Max = Time + Variation$

$Max = 15\ mins + 3\ mins$

$Max = 18\ mins$

The min value is identified as follows:

$Min = Time - Variation$

$Min = 15\ mins - 3\ mins$

$Min = 12\ mins$

If (a^3+27)=(a+3)(a^2+ma+9) then m equals

Inessa [3907]

Answer:

m = - 3

Step-by-step explanation:

a³ + 27 can be recognized as a sum of cubes, which factors generally as

a³ + b³ = (a + b)(a² - ab + b²). Therefore:

a³ + 27

= a³ + 3³

= (a + 3)(a² - 3a + 9).

By comparing a² - 3a + 9 to a² + ma + 9, we find that

m = - 3.

Venetta buys 2 pounds of pistachios and 3 pounds of almonds. The pistachios cost $4 more per pound than the almonds. She pays a

babunello [3635]

Answer:

A. Combining one pound of pistachios with one pound of almonds costs $20.

C. Decreasing the almond quantity by one pound leads to a total price of $40.

E. The price p (in dollars) per pound of pistachios is represented by the equation 2p + 3(p – 4) = 48.

Step-by-step explanation:

Let:

x = cost per pound of pistachios

y = cost per pound of almonds

We know that

x = y + 4 (Equation A)

2x + 3y = 48 (Equation B)

Substitute x from Equation A into Equation B:

2(y + 4) + 3y = 48

2y + 8 + 3y = 48

5y = 48 – 8

y = 8

Find x:

x = 8 + 4 = 12

Therefore, pistachios cost $12 per pound and almonds cost $8 per pound.

Verify the statements:

Case A) One pound of each equals $20.

True, since 12 + 8 = 20.

Case B) Pistachios cost twice as much as almonds.

False, because 2 × 8 = $16 ≠ $12.

Case C) Reducing almond pounds by 1 yields $40 total.

True, as 2(12) + 2(8) = 24 +16 = 40.

Case D) The almond cost modeled by 2(a – 4) + 3a = 48.

False; it should be 2(a + 4) + 3a = 48.

Case E) The pistachio cost modeled by 2p + 3(p – 4) = 48.

True, since p = a + 4 implies a = p – 4.

pat made a total of 48 pottery plates and cups if she made twice as many plates as cups how many plates did she make?

tester [3916]

48 divided by 3 equals 16 (cups)
Adding 16 and 16 gives 32 (which is double the number of cups)
Thus, the number of plates is 16.

What proportion of these candy bars have more than 300 calories per serving? (Round your answer to two decimal places.)

Inessa [3907]

Answer: 0.12

Step-by-step explanation:

There are a total of 65 candy bars. Within this amount;

2 candy bars contain 300 to 350 calories

1 candy bar contains 350 to 400 calories

4 candy bars contain 400 to 450 calories

1 candy bar contains 450 to 500 calories

Thus, the overall ratio of candy bars with more than 300 calories is;

= (2 + 1 + 4 + 1) / 65

= 8/65

= 0.12
