symmetry 2x^2+4x-1

Solution

symmetry

2 x^{2} + 4 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 = 2, b = 4

x = \frac{- 4}{2 \cdot 2}

Refine

x = - 1

Popular Examples

slope of y=3x-5 slope

y = 3 x - 5

extreme f(x)=(x^2+4)/(8x)extreme points

f (x) = \frac{x ^{2} + 4}{8 x}

midpoint (89,43),(73,-66)midpoint

(89, 43), (73, - 66)

monotone f(x)=x^2+6x+9 monotone intervals

f (x) = x^{2} + 6 x + 9

intercepts of f(x)=-3(x-4)^2(x^2-1)intercepts

f (x) = - 3 (x - 4)^{2} (x^{2} - 1)
