Question

EVALUÉ LOS VALORES Si f(x)=√(x+1), hallar f(0),f(-8),f(1/2) y f(-1/2)

Answer 1

$f(x) = \sqrt{x + 1}$

Evaluando:

$f(0) = \sqrt{(0) + 1} \\ f(0) = \sqrt{0 + 1} \\ f(0) = \sqrt{1 } \\ f(0) = 1$

$f( - 8) = \sqrt{( - 8) + 1} \\ f( - 8) = \sqrt{ - 8 + 1} \\ f( - 8 )= \sqrt{ - 7} \\ f( - 8) = \sqrt{7} i$

$f( \frac{1}{2} ) = \sqrt{( \frac{1}{2}) + 1 } \\ f( \frac{1}{2} ) = \sqrt{ \frac{1}{2} + 1 } \\ f( \frac{1}{2} ) = \sqrt{ \frac{3}{2} }$

$f( - \frac{1}{2} ) = \sqrt{( - \frac{1}{2} ) + 1} \\ f( - \frac{1}{2} ) = \sqrt{ - \frac{1}{2} + 1 } \\ f( - \frac{1}{2} ) = \sqrt{ \frac{1}{2} } \\ f( - \frac{1}{2} ) = \frac{1}{ \sqrt{2} } = \frac{ \sqrt{2} }{2}$
