Question 433045
Using the graph of 

{{{y = x^2 + 4x - 5}}}


{{{ graph( 500, 500, -10, 10, -10, 10, x^2 + 4x - 5) }}} 

1. the solution to the equation: 

{{{x=1}}} or {{{x=-5}}}

x-intercepts: (1,0) (-5,0)

2.this function have a minimum; it opens upward

3. the coordinates of the vertex are (-2, -9)

4. the equation of the line of symmetry for this parabola is {{{x=-2}}}
