symmetry-x^2-8x-21

Solution

symmetry

- x^{2} - 8 x - 21

Solution

x = - 4

Solution steps

Axis of Symmetry for

y = a x^{2} + b x + c

is

x = \frac{- b}{2 a}

a = - 1, b = - 8

x = \frac{- ( - 8 )}{2 ( - 1 )}

Refine

x = - 4

Popular Examples

symmetry y=-2x^2+8x-5 symmetry

y = - 2 x^{2} + 8 x - 5

inverse of ln(x+4)inverse

ln (x + 4)

range of f(x)=2sqrt(x+5)range

f (x) = 2 x + 5

domain of f(x)=(x-4)/(3x+5)domain

f (x) = \frac{x - 4}{3 x + 5}

asymptotes of f(x)= x/((x-1)^2)asymptotes

f (x) = \frac{x}{( x - 1 ) ^{2}}
