Identify the key features for function f(x) = -x2 -2x + 3 1. vertex
2. Is the vertex a maximum or minimum?
3. y-intercept
4. x-intercepts
5. vertical stretch/shrink
6. Graph the Function
(You don’t need to answer #6, as I don’t think you can show me how to graph the function)

The median segment divides the triangle into 2 isosceles triangles and everything else is trivial.|ad|=|bc|2=|bd|soδadb  is isosceles with∠dab=∠dbasimilarlyδadc  is isosceles with  ∠dac=∠dca∠cab=∠cad+∠bad=∠acb+∠abctherefore∠cab  is a right angleandbc  is the hypotenuse of a right-angled triangle.hope this
