Best ResponseYou've already chosen the best response.2vertex of \[x^22x+5\] should be easy enough to find

Best ResponseYou've already chosen the best response.2since log is an increasing function, once you find the minimum value of the quadratic, that will give you the input that produces the minimum value of the log

Best ResponseYou've already chosen the best response.2the second coordinate of the vertex is not 5, the constant is 5

Best ResponseYou've already chosen the best response.0i put x=0 here x^22x+5

Best ResponseYou've already chosen the best response.2yeah sure, if you put in 0 you get 5, but the vertex is NOT \((0,5)\)

Best ResponseYou've already chosen the best response.2use \[\frac{b}{2a}\] to find the first coordinate of the vertex

Best ResponseYou've already chosen the best response.2plug that in to find the second coordinate ( it is definitely not 5)

Best ResponseYou've already chosen the best response.2you certainly don't need to use calc to find the vertex of a quadratic though...
