Question 140900: does this function have a maximum or a minimum?
x^2+4x-5=0
or
(-5,1)
or
(-2,-9)
and what are the coordinates of the vertex in (x,y) form and what is the equation of the line of symmetry on the graph? Answer by edjones(7569) (Show Source):
You can put this solution on YOUR website! 1) It has a minimum because the coefficient of x^2 is positive.
.
2)
x^2+4x-5=0
(x+5)(x-1)=0
x=-5, x=1
(-5,1)
.
3)
(-5+1)/2=-2
Line of symmetry is a vertical line on y=-2
