Best ResponseYou've already chosen the best response.1I see it has a minimum. Do you see that?

Best ResponseYou've already chosen the best response.0yes because it's postive right

Best ResponseYou've already chosen the best response.1And that minimum is the vertex. Right?

Mertsj

Best ResponseYou've already chosen the best response.1And the x coordinate of the vertex can easily be found because we know that x = b/2a Right?

Best ResponseYou've already chosen the best response.0oh by the way it says x=.28 and then it says to determine the min and write as coordinate, idk if .28 makes any difference

Best ResponseYou've already chosen the best response.1And b/2a= 10250/1220=8.40

Best ResponseYou've already chosen the best response.1Maybe you'd better post the entire problem.

Best ResponseYou've already chosen the best response.0evaluate each expression below for x=.28. determine the max or min of f(X)=610x^210250x+1235. write answer as a coordinate.

Best ResponseYou've already chosen the best response.1Ok. We can do that at the end. Right now we're in the middle of finding the vertex. So do you agree that the x coordinate of the vertex is 8.40?

Mertsj

Best ResponseYou've already chosen the best response.1So now we can find the y coordinate of the vertex by replacing x with 8.40 and evaluating the expression.

Best ResponseYou've already chosen the best response.1How did you get a decimal point after the 4?

Best ResponseYou've already chosen the best response.0let me calculate it again ok

Best ResponseYou've already chosen the best response.1The numbers are right. just the decimal is off.

Best ResponseYou've already chosen the best response.1maybe your calculator is in scientific notation mode and it has an exponent of 4. Could that be?

Best ResponseYou've already chosen the best response.0is cuz i set it to round and it's literallly going crazy so let's go with ur answer ok

Mertsj

Best ResponseYou've already chosen the best response.1Ok. Now we know the vertex is (8.4,41823.4)

Mertsj

Best ResponseYou've already chosen the best response.1And now we have to plug in the .28 and find the value of the expression for that x value.

Best ResponseYou've already chosen the best response.1I got 6917.176 What did you get?

Mertsj

Best ResponseYou've already chosen the best response.1you've got to get your calculator out of scientific notation mode. Do you have a EE button?

Best ResponseYou've already chosen the best response.1It automatically gives you your answers in scientific notation and you are overlooking the number at the upper right of the screen that tells you the exponent of the 10

Best ResponseYou've already chosen the best response.0i redid it and now i got 1.59??????

Best ResponseYou've already chosen the best response.1I'll do it again. I'll bet that every problem you do, you get an answer between 1 and 10. Am I right? Enter 20 times 500

Mertsj

Best ResponseYou've already chosen the best response.1There you go. Of course 20 times 500 is 10000 not 1. Did you look for a little number at the upper right of your screen? It should be a 4

Best ResponseYou've already chosen the best response.1In any case, I've double checked it a number of times. f(.28)=1587.176

Best ResponseYou've already chosen the best response.0so ok then how do i write it as a coordinate?

Mertsj

Best ResponseYou've already chosen the best response.1And for the vertex: Ok. Now we know the vertex is (8.4,41823.4)
