Hi
Using the vertex form of a parabola, y=a%28x-h%29%5E2+%2Bk where(h,k) is the vertex
f(x)= -10x^2 + 5x + 6 |putting into the vertex form by completing the square
f(x)= -10[x^2 - 1/2x] + 6
f)x)= -10[(x - 1/4)^2 - 1/16] + 6
f)x)= -10(x - 1/4)^2 - 10/16 + 6
f)x)= -10(x - 1/4)^2 + 10/16 + 6
f)x)= -10(x - 1/4)^2 + 106/16 |vertex is Pt(1/4, 53/8)
