Is it right
the question
the function f(t) = t2 + 4t − 14 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)
