This time, I want to CHECK my answer with you smart people.
Consider the parabola y=−5x2+17x−12 . What is the vertex of this parabola?
Enter your answer as a coordinate pair, that is, as (x,y) where x and y are replaced by numbers.
Axis of symetry (x value)=−b2a=−17−10=1710=1.7
Plugging it in (y value)−5(1.7)2+17(1.7)−12−5(2.89)+17(1.7)−12−14.45+28.9−12−14.45+16.9+2.45
Answer:(1.7,2.45)
Therefore, I think that the answer is (1.7,2.45)

EDIT: If I did somehow get it right, post an emoji (or something) please in the answer section... If I got it wrong ( probably ) just say I got it wrong, why, and how I should do it next time.
You're exactly right!! 👍 🤪 🙌
And you can always check your answer to these type of questions with a graphing calculator such as desmos.
Same here- the only problem is that I have no idea how to save...
