Question

função f (X) = x/2+ 3.
​

Answer 1

Resposta:

a)

$\frac{2}{2} + 3 = 1 + 3 = 4$

b)

$\frac{ - 1}{2} + 3 = \frac{5}{2}$

c)

$\frac{4}{2} + 3 = 2 + 3 = 5$

d) f(2) = 4

f(0)

$\frac{0}{2} + 3 = 0 + 3 = 3$

f(3)

$\frac{3}{2} + 3 = \frac{9}{2}$

$\frac{f(2) - f(0)}{f(3)} = \frac{4 - 3}{ \frac{9}{2} } = \frac{1}{ \frac{9}{2} } = 1 \times \frac{2}{9} = \frac{2}{9}$
