The function f(t) = t2 + 6t − 20 represents a parabola. Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points) Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points) Part C: Determine the axis of symmetry for f(t). (2 points) @dabest21

    one addition/point for clarification the vertex is a point (x, y) so (-3, -29) minimum see on the graph @DaBest21 Thanks! @lealealea222 please keep practicing All the best with your studies
