Answer:
No, function is not one-to-one
No, function is not onto
Step-by-step explanation:
We are given that a function
f:![Z\rightarrow Z](https://tex.z-dn.net/?f=Z%5Crightarrow%20Z)
![f(x)=\mid{x-5}\mid +5](https://tex.z-dn.net/?f=f%28x%29%3D%5Cmid%7Bx-5%7D%5Cmid%20%2B5)
If function is one-to-one then different x have different image .
Domain =Z
Codomain=Z
When function is onto then range=Codomain
Substitute x=1
Then ,![f(1)=\mid{1-5}\mid+5=4+5=9](https://tex.z-dn.net/?f=f%281%29%3D%5Cmid%7B1-5%7D%5Cmid%2B5%3D4%2B5%3D9)
When substitute x=9
Then , we get ![f(9)=\mid {9-5}\mid +5=4+5=9](https://tex.z-dn.net/?f=f%289%29%3D%5Cmid%20%7B9-5%7D%5Cmid%20%2B5%3D4%2B5%3D9)
Image of 1 and 9 are same hence, function is not one-to-one.
Negative elements of Z and Zero has no preimage.Therefore, function is not onto.
Answer:
Ari will think that Feeze Zone makes milkshakes with too much caramel.
Step-by-step explanation:
First off I took 3 ounces of caramel to 5 scoops of ice cream, which makes a ratio of 3/5.
Freeze Zone makes milkshakes with 6 ounces of caramel, so I multiplied the 3 and the 5 by two to get 6 ounces of caramel for the ratio.
once you multiply the ratio by two it becomes 6/10 and the milkshakes that Freeze Zone makes are 6/8, so they have more caramel than Ari likes.
Sorry if the explanation is a little confusing, I hope it helped :)
