Question

find the vertex of the quadratic funciton f(x)=-2x^2+2x+3

Answer 1

find the vertex, line of symmetry, the maximum or minumum value of the quadratic funciton f(x)=-2x^2+2x+3

Answer 2

(1/2,9/2)

Answer 3

the maximum is the vertex itself ,i.e.(1/2,9/2)

Answer 4

line of symmetry is x=1/2

Answer 5

by completing the square of the main formula
(-1/2)(y-(11/6))=(x-(11/6))^2
