Answer 1

`(3.4)`

Explanation:

• Our equation is
  `f(x)=-2(x-3)^2+4`
• Now there are 2 ways you can do this, I'll show you the shortcut
• If you have an equation like this, just take the value in parenthesis and equate it to zero
• 
  `x-3=0.x=3` is the x of the vertex
• Put this back into the equation
• 
  `f(x)=-2(x-3)^2+4\\x=3\\f(3)=-2(3-3)^2+4\\f(3)=-2(0)^2+4=4` this is the y
