F(x)=x^3+4x−7
g(x)=6x^4−5x+2

what is f(x)−g(x)?

f(x)−g(x)=x−x
f(x)−g(x)=−6x^4+x^3+9x−9
f(x)−g(x)=6x^4−x^3−9x+9
f(x)−g(x)=6x^4+x^3−x

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.
