Question

Mark all of the statements that are true.
(will attach graph shortly)
a. The range for this function is the set {3}.

b. This graph is not a function because the value of y is the same for every value of x.

c. The domain for this function is all real numbers.

d. The domain for this function is the set {3}.

e. All real numbers are in the range of this function.
***CHOOSE ALL THAT APPLY!! And please explain!! :)
My answers are: A, B, C
Please go through with me? :)

Answer 1

hi @UnkleRhaukus do u think u can help me? :)

Answer 2

a, b, are correct

Answer 3

so C isn't correct?

Answer 4

i mean a, c are correct

Answer 5

so B is not correct??

Answer 6

d and e are not correct,

im not 100% sure on b

Answer 7

is it because x can go into a y value twice but y cannot go into an x value twice??

Answer 8

could u pls explain why d and e are not correct? i don't get it :/

Answer 9

B is false, this is indeed a function

Answer 10

hi @jim_thompson5910 thanks for coming too :)

Answer 11

how is this a function??

Answer 12

i passes the vertical line test ,

Answer 13

yes, and notice how each x only maps to one y

Answer 14

ohhhh i see i forgot about the vertical line test :O

Answer 15

oh yeah it does go to only one y...

Answer 16

so far the answers are A and C??

Answer 17

And what about D and E??? :)

Answer 18

c and d are in contradiction

Answer 19

oh so D is automatically NOT an answer? But what about E??

Answer 20

and e contradicts a

Answer 21

oh okay so the final answer is A and C? 100% sure? :)

Answer 22

I have just two more questions after this? one is double checking and the other i need an explanation... do you think ya'll can help me with just 2 more after? if not, i totally understand! :D

Answer 23

a. The range for this function is the set {3}.

True (only 3 is spit out of the function)


b. This graph is not a function because the value of y is the same for every value of x.

False, it passes the vertical line test. So it's a function

c. The domain for this function is all real numbers.

True. Any real number can be plugged into the function

d. The domain for this function is the set {3}.

False. This is a contradiction of choice c). Clearly values other than 3 work for x

e. All real numbers are in the range of this function.

False. This is a contradiction of choice a). Only 3 is produced as an output

Answer 25

OMG!! thanks so much @jim_thompson5910 that was great!! Ima give u a medal and can u please give @UnkleRhaukus one too cuz this only lets me give one and u both helped me so much! :)

Answer 28

and a very fine summary it is too indeed ,

Answer 29

thanks

Mark all the statements that are true.

A. This graph is a function whose range is the set {3}.
B. The equation of this line is x = 3.
C. This graph is a function whose domain is the set {3}.
D. This graph is not a function because the value x = 3 is assigned to more than one y-value.
E. This graph is a function because the value of x is the same for every value of y.
