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)
