1. Use the graph of y = x2 + 4x - 5 to answer the following:

[A] Without solving the equation or factoring, determine the solution(s) to the equation,

x2 + 4x-5 =0 , using only the graph.

[B] Does this function have a maximum or a minimum?

[C] What are the coordinates of the vertex in (x, y) form?

[D] What is the equation of the line of symmetry for this graph?

2. [A] Calculate the value of the discriminate of x2 + 4x +4 =0.

   [B] By examining the sign of the discriminate in part a, how many x-intercepts would the graph of y= x2 + 4x+4 have? Why?
