Question

pvfff me ajudemmmmm pvffffff

Answer 1

Explicação passo-a-passo:

a)

f(2) = 4.2+5

f(2)!= 8+5

f(2) = 13

b)

f(-2,5) = 4.(-2,5)+5

f(-2,5) = -10+5

f(-2,5) = -5

c)

f(-7) = 4.(-7)+5

f(-7) = -28+5

f(-7) = -23

d)

f(3/16) = 4.(3/16)+5

f(3/16) = (12/16)+5

$f \binom{3}{16} = \frac{ {12}^{ \div 4} }{ {16}^{ \div 4} } + 5$

f(3/16) = (3/4)+5

f(3/16) = (3+20)/4

f(3/16) = 23/4 ou 5,75

e)

f(-1/3) = 4.(-1/3)+5

f(-1/3) = (-4/3)+5

f(-1/3) = (15-4)/3

(-1/3) = 11/3
