During summer, the height of the water in a pool decreases by 4 inches each week due to
evaporation. What is the change in the height of
the water over a six-week period?

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.
