Sandra wrote p (x) = 30x + 5x2 in vertex form. Her work is below. 1. p (x) = 5x2 + 30x 2. p (x) = 5 (x2 + 6x) 3. = 9; 4. p (x) = 5 (x2 + 6x + 9) - 5 (9) 5. p (x) = 5 (x + 3) 2 - 45 Describe Sandra's function. What is the vertex of this function? Is it a maximum or a minimum? What is the axis of symmetry of this function?
