inflection sqrt(x)+sqrt(4-x)

inflection points

x + 4 - x

None

Solution steps

Find where

f^{''} (x)

is equal to zero or undefined

x = 0, x = 4

Identify inflection points not in domain or where

f (x)

is not continuous

Domain of

x + 4 - x : 0 \leq x \leq 4

f (x)

is not continuous at

x = 0, x = 4,

therefore:

None

(3, 0), (3, - 6)

f (x) = - 3 x^{2} - 42 x - 22

f (x) = x - 3

4 x - 5

- x^{2} + 3
