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.
The distance formula as shown below:
Answer:
80 ft
Step-by-step explanation:
the length of an arc is equal to the degree the arc makes
Answer:
$599.20
Step-by-step explanation:
Find what is 30% of 800, by turning 30% into a decimal
0.30- multiply this by 800
0.30*800=240
you then subtract 240 from 800
800-240=560
then add the tax 7%= 0.07
0.07*560=39.2
add this to your price
560+39.2= 599.2
