We are given the following function:
[tex]y=(6.5)x-9.5[/tex]We are asked to determine the value of the function when "x = 4". To do that, we will substitute the value of "x" in the function:
[tex]y=(6.5)(4)-9.5[/tex]Solving the operations:
[tex]y=16.5[/tex]Therefore, the value of the output is 16.5
