Question

a cross section of the parabolic glass mirror of the hubble space telescope shown can be modeled by the graph of the function y=0.0043x^2 where x and y are measured in meters find the domain and range of the function in  this situation

anonymous · Answer

this is a quadratic function. It's domain is all R, and range all positive real numbers. Depends on what the picture in your book looks like,,,
