Which description compares the domains of Function A and Function B correctly?

Function A: f(x)=(−x)−−−−√

Function B:

The domain of Function A is the set of real numbers greater than 0.

The domain of Function B is the set of real numbers greater than or equal to 0.

The domain of both functions is the set of real numbers less than or equal to 0.

The domain of Function A is the set of real numbers greater than 0.

The domain of Function B is the set of real numbers less than or equal to 0.

The domain of both functions is the set of real numbers greater than or equal to 0.

Percy rides his bike 11.2 miles in 1.4 hours at a constant rate. write an equation to represent the proportional relationship between the number of hours percy rides, x, and the distance in miles, y, that he travels.

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
