i am also stumped on this question

The bounce periods y are measured for a set of masses x hung from a spring. Assuming the exponential form y = bx m, (log y) vs. (log x) is plotted, yielding a linear trendline equation of (log y) = 0.4796 (log x) + 0.1029, with R2 = 0.9991. Which of the following exponential functions is most likely?

not enough info for the first one, what angle is the hill at? also, need either a final or initial velocity of some kind

second problem:

what are the choices? it sounds like it is multiple choice
