---------------------
Using the graph, what are the solution(s) to the equation x^2+4x-5=0
x=-5, x=1
------------------
Does this function have a maximum or a minimum?
Ans: minimum
----------------
What are the coordinates of the vertex in (x, y) form?
x=-b/2a = -4/2 = -2 ; y = (-2)^2+4*-2-5 = -9
---------------------
What is the equation of the line of symmetry for this graph?
x = -2
