Question

what is the vertex of f(x) =x^2 + 6x -3

Answer 1

vertex = -b/2a
= -6/2
= -3 this is x coordinate
substitute this value in f(x) to find y ordinate

Answer 2

it is simple this is the equation of a parabola so the vertex is at the point where the derivative of this function is 0
so the derivative becomes 2x +6
now equate it with 0 u will get x=-3
and putting this value in the function u will get y=-12

Answer 3

Thank you to both of you
