Answer 1

Answer:

$(3.4)$

Step-by-step 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
