?
1. Key Features of any parabola are the vertex, the zeros, and the y-intercept. Explain what happens to some key features of the graph for the equation y = (x + 2)²
2. Currently a builder knows the height of a cottage attic is 7 ft and he had determined the angle or elevation from the horizontal beam to be 35°
7 FT
35°
HORIZONTAL BEAM
He refers to his original architectural drawing to check if his construction will meet the necessary specifications
ARCHITECTURAL DRAWING
