Question: For each quadratic relation given in standard form, determine key features (x-intercepts, y-intercept, equation of the axis of symmetry and the coordinates of the vertex)

For each quadratic relation given in standard form, determine key features (x-intercepts, y-intercept, equation of the axis of symmetry and the coordinates of the vertex) of the graph using both the standard form of the expression and the factored form of the expression. Include a picture of the tiles that you used to determine the alternate form of the equation. Graph the relation by hand. Show your work for each.

1.y = x² - 8x - 9
