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)

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

so the vertex of the parabola is ( -2 , -18)

the axis of symmetry is y = -18

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
