please help!! this is for my math final! Which of the following tables represent exponential functions?

18 16 11 45 33 11 33 14 18 11 what is the mode for this data set

The slope of cd is which segments are perpendicular to cd ? select each correct answer. gf , where g is at (6, 5)and fis at (10, 2) ef, where e is at (4, 1) and f is at (7,5) lm , where lis at (-2, 3) and m is at (-10, 9) jk , where jis at (1, -2) and k is at (10, – 14) next

Similarly fie each expression 18,19,20
