Let d be the domain and let ƒ be the possible function. determine if the relation is an example of a function.

d = {x| x is a date, expressed in day/month/year}
ƒ(x) = temperature in seattle washington on that date

a: yes. one input results in one output.

b: yes. one output results in one input.

c: no. at least one output results in more than one input.

d: no. at least one input results in more than one output.

D

Step-by-step explanation: No,this is not a function.Since corresponding to one value of the domain there must exist its unique image.

                  i.e. if x∈D then f(x) must be unique.

As, temprature varies in a day.On any date temprature can't be constant.It keeps on changing.

                    So,here atleast one input results in more than one output

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
