~URGENT~ Mark all of the statements that are true.

A. All real numbers are in the range of this function,

B. This graph is not a function because the value of y is the same for
every value of x

C. The range for this function is the set (-5)

D. The domain for this function is all real numbers

E. The domain for this function is the set f-5

For the function, f(x) = -5x 2, find f(-4).

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
