Question

Please help fast I will give medal and fan.
The function f(t) = t2 + 12t − 18 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)

Answer 1

we can rewrite f(t) as follows:
\[{t^2} + 12t - 18 = {t^2} + 12t + 36 - 36 + 18\]

Answer 2

Thanks but how did you do that??
