Question

Dada a função definida por f (x)= 3x/2 + 1/4 , calcule:
A)f (1)=
B)f (2)=
C)f (-1)=
Df (-2)=

Answer 1

Dada a função definida por f (x)= 3x/2 + 1/4 , calcule:
A)f (1)=3.1/2+1/4=>3/2+1/4=>12/2=>6
B)f (2)=3.2/2+1/4=>6/2+1/4=>24/2=>12
C)f(-1)=3. (-1)/2+1/4=>-3/2+1/4=>-12/8=> -3/2
Df (-2)=3. (-2)/2+1/4=>-6/2+1/4=>-24/8=> -3
