Answer 7

Probably not a function, although it could be some kind of square-wave function, but i doubt it. There does not really seem to be a logical connection between x and y, so id'say no.

Answer 8

f(h) = 15h + 5
f(8) means replace any h with 8, so
f(8) = 15*(8) + 5 = 125
i beleive they mean you should write a table, a bit similar to part A.

@zimmah I didn't know the definition of function earlier, but when I did some research I knew that a function is one y-value for one x-value. (not vice versa)
