Someone please help explain this to me !
The table shows the outputs y for different inputs x:
Input
(x) 5 6 7 8
Output
(y) 2 5 8 11
Part A: Do the data in this table represent a function? Justify your answer.
Part B: Compare the data in the table with the relation f(x) = 2x + 13. Which relation has a greater value when x = 7?
Part C: Using the relation in Part B, what is the value of x if f(x) = 75?

Best ResponseYou've already chosen the best response.0for a, you need to understand the definition of a function. for a function, each input has a single output. for part b, compare the values at x=7 for c, you have\( f(x) = 2x+13\\ 75=f(x)=2x+13\\ 75=2x+13\\ 62=2x\\ x=31\)

Best ResponseYou've already chosen the best response.0"Part B: Compare the data in the table with the relation f(x) = 2x + 13. Which relation has a greater value when x = 7? " to find the value at x=7 for f(x), we just plug in x=7 in the relation \(f(7)=2(7)+13=14+13=27\) to find the value at x=7 for the table, just look at the equivalent y value where x=7
