i think the answer is f(x) = -11/100(x-6)^2+3 plz help

Question

write the standard form of the equation of the parabola that has a vertex of (6,3) and passes through the point (-4,-8)
i think the answer is f(x) = -11/100(x-6)^2+3 plz help

tkhunny · Answer

1) That would be the Vertex Form, not Standard Form.
2) Is it right?  How did you get that?

anonymous · Answer

out of the answer choice i pick that one i completely guess. im really confused with this question

tkhunny · Answer

First Problem, there are TWO such parabolas as the problem has been presented.  Which one shall we pick?

anonymous · Answer

(6,3)

tkhunny · Answer

??  The vertex is (6,3) in both solutions.

y-3 = a(x-6)^2

OR

x-6 = b(y-3)^2

Both can be solved to pass through (-4,-8).

im so confused

tkhunny · Answer

Do those two things I have written look like parabolas?

anonymous · Answer

yes they look like parabolas

anonymous · Answer

i give up im just going to guess. thank you for the help i really appreciate it

tkhunny · Answer

It's a shame.  Just substitute the values.
