(a bunch of points+brainliest) write the domain and the range of the function as an inequality, using set notation, and using interval notation. also describe the end behavior of the function. the graph of the quadratic function f(x) = -x^2 is shown

The pyraminx is a rubik's cube-type toy in the shape of a tetrahedron. the pyraminx shown below has edges 15\,\text{cm}15cm long and vertical height h=12.2\,\text{cm}h=12.2cm. the triangle drawn with dashed lines is a right triangle. what is the distance rr? round your answer to the nearest tenth.
