1. calculate the vertex of the quadratic function is standard form: y=−2x2+8x−3 a. (2, 5) b. (5, 2) c. (-2, -27) d. (2, 12) 2. calculate the vertex of the quadratic function in vertex form and state if it is a max or min value: y=−3(x−2)2+4 a. (-2, 4); maximum b. (-2, 4); minimum c. (2, 4); maximum d. (2, 4); minimum 3. a graph is shown. what is vertex of this function? is it a maximum or minimum value. a. (3, 1) - maximun b. (1, 3) - minimum c. (1, 3) - maximum d. (0, 2) - minimum
