Answer:

  • Option D

Step-by-step explanation:

The graph of a function should pass the vertical line test in order to be a function.

Option A

  • Fails as repeat x-values of 14 with different y-values

Option B

  • Fails as repeat x-values of 15 with different y-values

Option C

  • Fails as repeat x-values of 16 with different y-values

Option D

  • All x-values are different so this is a function

The rule is .

Every domain of the function should have an unique range i.e f(x)=y

#1

f(14) has two values hence not a function

#2

f(15) has two values hence not a function

#3

f(16) has two values hence not a function

#4

Yes it's a function,every domain has an unique range
