vertices f(x)=-x^2+10x

vertices

f (x) = - x^{2} + 10 x

Maximum (5, 25)

Solution steps

y = - x^{2} + 10 x

The parabola parameters are:

a = - 1, b = 10, c = 0

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

x_{v} = - \frac{10}{2 ( - 1 )}

Simplify

- \frac{10}{2 ( - 1 )} : 5

x_{v} = 5

Plug in

x_{v} = 5

to find the

y_{v}

value

y_{v} = 25

Therefore the parabola vertex is

(5, 25)

a < 0,

then the vertex is a maximum value

a > 0,

then the vertex is a minimum value

a = - 1

Maximum (5, 25)

- \frac{x ^{2}}{2} - 2 x

y = - x^{2} + 5

f (x) = x^{2} - x - 2

f (x) = 3 x^{2} - 2 x - 1

7 x^{2} - 40 x - 25
