Which system of equations could you use to
determine where the paths intersect?
y = 0 and y = -0.12(x - 20)^2
y = 0.8x and y = -0.12x^2 + 20
y = 0.8x and y = -0.12(x - 20)^2
y = 0.8x + 8 and y = -0.12x^2 + 20

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
