You can put this solution on YOUR website! Use the graph of y = x^2 + 4x - 5 to answer the following:
----------------------
a) Without solving the equation or factoring, determine the solution(s) to the
equation, 4 5 0 2 x x , using only the graph.
Answer:27,40,-5,7
-----------------------------------
Explain how you obtained your answer(s) by looking at the graph in a brief sentence:
I'll leave that to you.
-----------------------------------
b) Does this function have a maximum or a minimum?
Answer: Minimum because the coefficient of x^2 is positive.
-------------------------------------
Explain how you obtained your answer by looking at the graph in a brief sentence::
c) What are the coordinates of the vertex in (x, y) form?
Answer: (-2,-9)
-------------------------
d) What is the equation of the line of symmetry for this parabola?
Answer: x = -2
