Answer:
It’s D. 4
Step-by-step explanation:
GOOD LUCK HOMIE AND USE A CALCULATO ;)
It would be D, because to be a function, a set of ordered pairs cannot have the same x value. The y value can be the same though.
(5,6), (8,6), (9,6)
As you can see, all of the x values are different, so it is a function.
Think of it this way. Let's say t= one. 1+8 is 9. Your answer is 9t. Think of a variable without a number as one.
