The daily production cost, C, for x units is modeled by the equation: C = 200 – 7x + 0.345x2Explain how to find the domain and range of C.
Answer
Answer:
Since x represents units produced, the domain is x ≥ 0. The quadratic opens upward and has a minimum at its vertex, approximately (10.14, 164.5), so the range is C ≥ 164.5.
