A company finds that if it charges x dollars for a cell phone, it can expect to sell - 2x + 1000 phones. The company uses the function r
defined by r(x) = x(-2x + 1000) to model the expected revenue, in dollars,
from selling cell phones at x dollars each. Is Os sps
600 an appropriate
domain for the function r? Explain your reasoning.
