symmetry y=x^2+2x-1

Solution

symmetry

y = x^{2} + 2 x - 1

Solution

x = - 1

Solution steps

Axis of Symmetry for

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

is

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

a = 1, b = 2

x = \frac{- 2}{2 \cdot 1}

Refine

x = - 1

Popular Examples

domain of f(x)=49x+72 domain

f (x) = 49 x + 72

domain of f(x)=(x^2-11x-12)/(x+4)domain

f (x) = \frac{x ^{2} - 11 x - 12}{x + 4}

extreme f(x)=x^2+8x+1 extreme points

f (x) = x^{2} + 8 x + 1

y = - 2 x

domain of (20x^3+30x^2)/(15x^5)domain

\frac{20 x ^{3} + 30 x ^{2}}{15 x ^{5}}
