At the beginning of summer, a maintenance crew refills the swimming pool at a city park The relationship between time and the amount of water in the pool is proportional. After
4 hours, the pool holds 5 200 gallons.
a)Draw a graph which represents the relationship between time and the volume of water
in the pool.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0

Use the function f(x) is graphed below. the graph of the function to find, f(6). -2 -1 1 2
