Please help fast I've been trying to complete this for an hour and I need to get it done before 6am
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)

Best ResponseYou've already chosen the best response.0i dont understand what you mean by what is b/(2a) but ive been attempting to teach myself how to do these problems for an hour and at this point i dont think im capable of learning it without a physical teacher but so far for this question my answers are, "PART A: vertex form a(xh)^2 + k h = b/2a from standard form ax^2 + bx + c k = f(h) vertex (h, k) PART B: it is a minimum on the graph because it is the lowest point of the parabola at (2,18) PART C: axis of symmetry is the line x = h "

Best ResponseYou've already chosen the best response.0the question gave you the part originally marked in blue. to make a perfect square you added 4 to keep the balance of the equation you 4. +4 added to 4 = 0 so you are not changing the original just expressing it differently

Best ResponseYou've already chosen the best response.0but you see why I had that point h = 2 and k = 18 Part C: Determine the axis of symmetry for f(t). (2 points) the axis of symmetry is the line that will "cut the parabola in half where the vertex is"
