I need help. y=x^2+10x+20.
1 answer:
The vertex is (-5, -5)
this is the lowest point found, the way to figure this out is to graph it or take the derivative
The derivative is 2x + 10 = 0
x = -5
The axist of symmetry is also -5 because it runs through the vertex.
The direction of opening is concave upward. this is because the x value is positive.
