10. What is the inverse of fif f(x) = root(3, x - 4) ? (1 point) f ^ - 1 * (x) = x ^ 3 + 64 ○ f ^ - 1 * (x) = x ^ 3 + 4; f ^ - 1 * (x) = 4 - root(3, x); f ^ - 1 * (x) = 1/(root(3, x - 4))

Average acceleration: i have no idea how to do this.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
