Use the graph of f(x) to explain the relationship between the real zeros of f(x) and its intercept(s).

f(x) has one real zero at –2 because the graph of the function has an intercept at (0, –2).
f(x) has two real zeros at –4 and –2 because the graph of the function has intercepts at (–4, 0) and (0, –2).
f(x) has no real zeros because the graph of the function does not pass through (0, 0).
f(x) has one real zero at –4 because the graph of the function has an intercept at (–4, 0).

How do the graphs of y = 1/x and y=5/x+6 compare?

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
