Web1 Answer Sorted by: 4 Plug in ( x, y) = ( 18, 13.6) to get 13.6 = a ( 18 − 12) 2 + 16 and then solve for a. You can do this because you know the point ( 18, 13.6) is on the parabola, so it must satisfy the equation.

WebA quadratic equation (also referred to as a quadratic function) is a polynomial whose highest exponent is 2. The standard form of a quadratic equation looks like this: f (x) = ax² + bx + c When graphed on a coordinate plane, a quadratic equation creates a parabola, which is a u-shaped curve. tasmanian brietasmanian budgetWebQuadratic equations are written in vertex form as: y=a (x-h)^2+k where (h,k) represent the vertex of the parabola, and the sign of a represents if the graph of parabola is open upwards or downwards. In your equation y = - (x-2)^2+3, Vertex (h,k)= (2,-3) Since a=-1, this tells us that the graph will be open downwards. 1 comment ( 5 votes) Upvote 黒い砂漠 490WebEnter your quadratic function here.
