Which quadratic equation models the situation correctly.
this situation. With a group of 3-4 they will video a shot and then edit it so that only half of the shot is visible. They will then trade videos with another group and mathematically write an equation for the quadratic and use their equation to determine if the shot went into the hoop or not. This introduction should take about 20 minutes.
Vertex form is a form of a quadratic equation that displays the x and y values of the vertex. f (x)= a (x-h)^2+k. You only need to look at the equation in order to find the vertex. f (x)= 2 (n-2)^2-10. In this case, the vertex is located at (2,-10). Explanation: since -2 is in the parenthesis, the quadratic equation shifts 2 units to the right.Which equation is the inverse of y = 7x2 - 10? B.
