Find the vertex and write the quadratic function in vertex form (which our OpenStax textbook also calls the standard form). f(z) - x2 - 10x + 89 Give the vertex. Enter your answer as a point (a, b) . Vertex: Enter the coordinates of the vertex to write f (x ) in vertex form: f (3) - (x- Number )24 Number Which of the following best represents the graph of this function, considering the location (quadrant) of the vertex and the direction that the graph opens?\f\f
