Is this relationship a function? (1,2) (2,9) (3,-2) (4,8)?

yes, it's a function

Step-by-step explanation:

A function relates one input to one output, and it's "only" one output.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
