Hey there!
To find the value of f(-2), first locate a point on your graph with -2 as its x value. To do this, locate -2 on the x axis and move towards the function. When you do, you should find the point (-2, 4).
Therefore, your answer would be the y-value of the point, 4.
To find the value of f(5), you would do the same as above. When you locate your point, you should find (5,3).
Therefore, your answer would be the y-value of the point, 3.
Hope this helps! :)
That is dependent because it is changing.independent stays the same
We start by ordering the values.
5, 7, 8, 10, 13, 14, 17, 17, 21
Now we find the median(middle number).
Median(b): 13
(I added (b) for "base" since we need to take more medians)
The median now divides this data into two halves.
Now we take the medians of the two remaining halves.
Median(Half1): 7.5
Median(Half2): 17
Mark off the minimum and maximum.
Min: 5
Max: 21
Now graph!
Your median(Half1) is incorrect, since your median for the first half is 9. Since our median for the first half is 7.5, the answer would be Answer Choice C.
Answer:
y = (10 * 0.2) ^ x
Y = (2)^x
Y = 2^x + 10
6.5 hours
Step-by-step explanation:
Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.
The last one
