Question 530678: Find the vertex of the parabola y= -2x2 + 12x - 13
Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
y = 2x^2 + 12x - 13
.
The axis of symmetry is defined by x = -b/2a.
.
-12/(2*2) = -3
.
Set x= -3 and find y.
.
2(-3)^2 +12(-3) -13 = 18 -36 -13 = -31
.
The vertex is: (-3,-31)
.
