Answer:

<em>f(2)=-2</em>

Step-by-step explanation:

<u>Values of a function from a graph</u>

The graph of a function is usually a drawn line that joins a number of points that correspond to the ordered pairs (x,y), where x is a given value, and y is the value calculated through the rule of the function, usually a formula or equation.

If we want to know the value for a specific value of x, we find the corresponding x-coordinate, draw an imaginary vertical line until we meet the graph. The value of y at that point is the required value of the function.

For example, for x=0 the graph crosses the y-axis at y=2, thus the ordered pair is (0,2), and f(0)=2.

For x=2, the function has a value of y=-2, thus:

f(2)=-2

pychu [463]

The answer would be 9,631.473. Since there is a 5 after the two, you round up one value. Hope this helps!

Please help me out! I keep getting the wrong answer
Tamiku [17]

The total amount of people who ordered a large is 5 + 12 + 8 = 25 people.

The amount of customers who bought a large cold drink is 5.

The probability that someone bought a large cold drink is 5 out of 25 people.

This is 5/25 which is 1/5 which is .2

Convert the decimal to a fraction by multiplying by 100 and adding a percent sign at the end.

.2 x 100 = 20%

Edit:

The probability was supposed to be if the customer ordered a cold drink based on people who ordered large.

The amount of people who ordered a large drink is 22 + 5 = 27.

The amount of people who ordered a cold large is 5.

To find the percent, divide the people who ordered cold large by the total people who ordered large.

This would be 5/27 which in decimal form is .185185

To convert to a percent, multiply by 100 and add a percent sign after it.

.185185 x 100 = 18.5185%

The question says to round to the nearest percent so your answer is:

19%
