Question 766417: Can someone please help me solve this? Thank You!!

Find the maximum y-value of the graph of y=f(x)
f(x)=-x^2+2x+2
The maximum y-value is y= ____

Complete the Square to put the function into standard form, and you can read the vertex directly.

Use the term, "1", AFTER first factoring out -1.
-1(x^2-2x+1-1-2)
-1((x-1)^2-3)
-(x-1)^2+3

Point is (1,3) maximum
