Question

y = -2x^2+5

Answer 1

What about it?

Answer 2

find the vertex or explain how to please!

Answer 3

One method is to find the axis symmetry and then substitute for y point

Answer 4

Shouldnt the graph be upside down since its a negative 2?

Answer 5

did u get my message?

Answer 6

axis of symmetry formula is x=-b/2a
so x=-0/2(-2)=0
x=0
put it back into the equation and you get y. Then you have (x,y) of vertex

Answer 7

That was a general case picture, but yes. The parabola would be upside-down in your problem.

Answer 8

Thank you so much, and thank you hmm!!

Answer 9

Ur welcome :)
