Question

what does the arrow right symbol stand for

Answer 1

yields

Answer 2

so if I have xyield 1what do i do

Answer 3

or as x goes to 1

Answer 4

are you doing a limit?

Answer 5

It just says suppose f is a rule of correspondence with domain elements x,y,z,t Then it states that each of these letters are to yeild to 1.

Answer 6

Then it asks if f is a function

Answer 7

Does that make sense

Answer 8

If i'm correctly understanding what you are asking your domain elements will be x,y,z,t... and if they are all 1 so say you have (1,a),(1,b)(1,c)(1,d) is this a function?

Answer 9

correct

Answer 10

so in this case it cannot be a funtion as a function can only have one value for (1,?)

Answer 11

wouldn't it be no because you have to have more then one real number

Answer 12

does it state their range

Answer 13

no

Answer 14

thank you so much

Answer 15

One value of x must always have only one value of y

Answer 16

so if they are all 1 and the ranges differ (which i believe is what they are asking), your answer will be no it is not a function

Answer 17

ok that is what I thought too. Thanks

Answer 18

The arrow in this case indicates a mapping. x->y should be read "x maps to y".
