The demand for bicycles is modeled by the function f(x) = - x ^ 2 + 5x + 14 where x represents the number of stores in a city th
at sell bicycles. A company wants to know when the demand is positive
the interval (- 2, 7) a reasonable solution to when the demand is positive?
Yes. The interval (- 2, 7) is a reasonable solution because the function is positive in that region
No The interval (- 2, 7) is not a reasonable solution because the lett endpoint is negative and there cannot be a negative number of stores.
The interval (- 2, 7) is not a reasonable solution because the function is negative in that region;
Yes The interval (- 2, 7) a reasonable solution because the endpoints of the interval are roots of the function
