feet below sea level to a nest that is 662 and nine tenths
feet above sea level. what is the difference in elevation between the bottom of the canyon and the bird's nest?

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
