vertices f(x)=-0.02x^2+x+6

vertices

Maximum (25, 18.5)

Solution steps

y = - 0.02 x^{2} + x + 6

The parabola parameters are:

a = - 0.02, b = 1, c = 6

x_{v} = - \frac{b}{2 a}

x_{v} = - \frac{1}{2 ( - 0.02 )}

Simplify

- \frac{1}{2 ( - 0.02 )} : 25

x_{v} = 25

Plug in

x_{v} = 25

to find the

y_{v}

value

y_{v} = 18.5

Therefore the parabola vertex is

(25, 18.5)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = - 0.02

Maximum (25, 18.5)
