Question 272425: please help
Parabola: y=x^2+6x+5 , give vertex & x & y axis
Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
factoring x^2 + 6x + 5, we arrive at:
y = (x+1)(x+5)
.
This means the intercepts will be -1 and -5
.
.
The vertex is at x= -b/2a = -6/2 = -3.
When x = -3, y = -4, which is the point: (-3,-4).
.
By inspecting the graph, we can see this fits.
