inflection f(x)=ln(x^2-4x+5)

inflection points

f (x) = ln (x^{2} - 4 x + 5)

(1, ln (2)), (3, ln (2))

Solution steps

f^{''} (x) = \frac{- 2 x ^{2} + 8 x - 6}{( x ^{2} - 4 x + 5 ) ^{2}}

Find intervals:

Concave Downward

: - \infty < x < 1,

Concave Upward

: 1 < x < 3,

Concave Downward

: 3 < x < \infty

Plug

x = 1

into

ln (x^{2} - 4 x + 5) : ln (2)

(1, ln (2))

Plug

x = 3

into

ln (x^{2} - 4 x + 5) : ln (2)

(3, ln (2))

(1, ln (2)), (3, ln (2))

l in e - 3 x + 7

in v erse g (x) = \frac{1}{x - 1}

l in e (- 2, 4), (3, 5)

d o main x^{2} - 2 x - 8
