Suppose f is the function f(x) = |x - 5| + 5 and f : z -> z
is f one-to-one:
is f onto:

No, function is not one-to-one

No, function is not onto

Step-by-step explanation:

We are  given that a function

f:

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 ,

When substitute x=9

Then , we get

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.

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
