Best ResponseYou've already chosen the best response.0hmm... for the other questions, I plugged in c to x and set that number (in this case, 6) equal to the equation and solved it. but for this one, I can't

Best ResponseYou've already chosen the best response.1\[f(x) = \frac{ x^2+x }{ x1 }\] you need some numbers to get the second part

Best ResponseYou've already chosen the best response.1they way you show there must be a number in \([\frac{5}{2},4]\) with \[f(c)=6\] is to compute \(f(\frac{5}{2})\) and \(f(4)\)

Best ResponseYou've already chosen the best response.1one number will be larger than 6, one number will be smaller than 6, so by the intermediate value theorem the function must be 6 somewhere in that interval

Best ResponseYou've already chosen the best response.1since the function is continuous on that interval and cannot skip values

Best ResponseYou've already chosen the best response.0well, in class, I learned that c has to be replaced with x and have to set that equation to 6. when I get the x values, the values between 5/2 and 4 is the answer is this right?

Best ResponseYou've already chosen the best response.1you job is to solve \[f(x)=6\] but that is for the second part of the question

Best ResponseYou've already chosen the best response.1there are two parts 1) verify that the intermediate value theorem applies to the indicated interval

Best ResponseYou've already chosen the best response.1the reason that you know \[f(x)=6\] for some \(x\) in the interval is because \(f(4)\) is larger than 6, and \(f(\frac{5}{2})\) is smaller than 6

Best ResponseYou've already chosen the best response.1i think \(f(\frac{5}{2})=5\tfrac{5}{6}\) and \(f(4)=\frac{20}{3}\)

Best ResponseYou've already chosen the best response.0how can 4 be larger than 6?

satellite73

Best ResponseYou've already chosen the best response.1it is not 4 that is larger than 6, it is \(f(4)=\frac{20}{3}\) that is larger than 6

Best ResponseYou've already chosen the best response.1in other words \[f(\frac{5}{2})<6<f(4)\]

Best ResponseYou've already chosen the best response.1so since 6 lies between the two function values, there must be some \[c\in (\frac{5}{2},4)\] where \(f(c)=6\)

Best ResponseYou've already chosen the best response.1now solving it is just a matter of solving \[\frac{x^2+x}{x1}=6\]

Best ResponseYou've already chosen the best response.1you would start with \[x^2+x=6(x1)\] and solve the resulting quadratic equation
