Answer:
Problem 9: No
Problem 10: Yes
Step-by-step explanation:
Hello!
Problem 9:
This is NOT a function because one x-value has only one unique y-value. -2 is seen twice and the outputs, y, are given as 6 and 0.5. To be a function, each input has its own unique output. Two different inputs can have the same output.
Problem 10:
This IS a function, all inputs have unique outputs, and no repeating inputs are shown.
Terms:
x - values are also known as input, abscicca
y - values are also known as output, ordinate.
