In order for the data in the table to represent a linear function with a rate of change of -8, what must be the
value of a?
O a = 2
O a = 3
O a= 19
O a = 35

Given the graph below state whether or not the relation is a function, and give the domain and range.

Marquise has 200 meters of fencing to build a rectangular garden. the garden's area (in square meters) as a function of the garden's width w w (in meters) is modeled by: a ( w ) = − w 2 + 1 0 0 w a(w)=−w 2 +100w what side width will produce the maximum garden area? meters
