At what value of x does the minimum or maximum occur for the function below? f(x) = 6(x - 9)2 - 5 i got maximum= -5 but i need it double checked please

OpenStudy (inkyvoyd):

Be careful. You aren't looking for the maximum, but for what value of x the maximum is.

OpenStudy (anonymous):

so he maximum is 9 ?

OpenStudy (inkyvoyd):

No.

OpenStudy (inkyvoyd):

The maximum is -5, but the question is not asking for the maximum.

OpenStudy (inkyvoyd):

the maximum is the output (y); we are looking for the input (x)
