Question

What is the minimum or maximum of `g(x)=12.8x^2+8.73x+11.69`?

Answer 1

Find Max and Min of `g(x) = 12.8x^2 + 8.73x + 11.69`

Explanation:

Since a > 0, the parabola opens upward, there is a Min at the vertex.
x-coordinate of vertex: `x = (-b/(2a)) = -8.73/25.56 = 0.34`
y-coordinate of vertex:
y = f(0.34) = 12.8(0.12) + 8.73(0.34) + 11.69 = 16.14
