Question

evalúe la función f(x)=2x+8 en x=1 y en x = 1/5 ​

Answer 1

Respuesta:

$f(x) = 2x + 8 \\ f(1) = 2(1) + 8 \\ f(1) = 2 + 8 \\ f( 1) = 10 \\ \\ f( \frac{1}{5} ) = 2( \frac{1}{5} ) + 8 \\ f( \frac{1}{5} ) = \frac{2}{5} + 8 \\ f( \frac{1}{5} ) = \frac{2 + 5(8)}{5} \\ f( \frac{1}{5} ) = \frac{42}{5} \\ f( \frac{1}{5} ) = 8 \frac{2}{5}$
