write your vertex as (-5,3)
the line of symmetry is the x of the vertex, so
line of symmetry is x = -5
the max of the function is 3, (the y value of the vertex)
since the value of "a" of your function is negative, the parabola opens downwards, thus a Maximum.
Okay. I had the vertex written in correctly. the line of symmetry & max function I had backwards for some unknown reason. The other 2 parts I had totally wrong.
Thank you for checking this for me Reiny! I was leery at posting it until I had it checked. Good thing I did!
I put the vertex as (-5,3) and it is saying it was wrong...ughhhhhhhh.
the vertex is indeed (-5,3)
f(x)=a(x-h)+k, the vertex is at:
Since the function is already in that form, where
as Mr. Pursley stated:
"the vertex is indeed at (-5,3)".
Reread the question to see if
1. there are errors of transcription, especially signs
2. there are instructions on the format of presentation of answers.
There are times (but rare) that the computer rejects the correct answers. Hope this is not one of them.
