symmetry (x-1)^2-4

الحلّ

symmetry

(x - 1)^{2} - 4

x = 1

خطوات الحلّ

y = (x - 1)^{2} - 4

Rewrite in standard form:

y = x^{2} - 2 x - 3

y = x^{2} - 2 x - 3

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

هو

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

محور التماثل لـ

a = 1, b = - 2

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

بسّط

x = 1

f (x) = \frac{3 x - 1}{2 x + 8}

f (x) = 5 x^{2} - 1

\frac{1}{x ^{2} + 2 x + 2}, - 2 \leq x \leq 2

3 x - 10 y = 20
