Question

Answer the following questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!

Answer 1

Answer by JKismyhusbandbae: This is not a function because the two in the domain area is paired with 21 and 25. A function is basically whenever there is no domain that repeats.

Answer 2

in a function, every input must give only 1 output

an example of a function is an elevator: if you push button for 1st floor, it takes you to 1st floor and not 1st and 4th floor

in the given example, it is not a function because the value of 2 in the domain outputs 2 different values in the range (21 and 25)

it would be like pushing a button on the elevator and the elevaor sometimes takes you to floor 3 and sometimes takes you to floor 5
