The demand for cars is modeled by the function f(x)=−x2+2x+15 , where x represents the number of stores in a city that sell cars. A company wants to know when the demand is positive.
Is the interval (−3, 5) a reasonable solution to when the demand is positive?
No. The interval (−3, 5) is not a reasonable solution because the left endpoint is negative and there cannot be a negative number of stores.
Yes. The interval (−3, 5) is a reasonable solution because the function is positive in that region.
No. The interval (−3, 5) is not a reasonable solution because the function is negative in that region.
Yes. The interval (−3, 5) is a reasonable solution because the endpoints of the interval are roots of the function.
