The wake of a boat which is moving at constant speed keeps gettingwider after the boat passes. The wake is the same width as the boatwhen it first forms, and then it gets wider in proportion to the square root of the distance from the boat. If a 2-meter wide boat passes yourposition at 5 m/sec, which domain is appropriate for a function thatmodels the width of the wake, f(x), and the distance from the boat, x?a) all numbers greater than 2b) all rational numbers c) all positive numbers d) all numbers greater than 5
