Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4

Line wx is parallel to line yz. if m
