2- Sabendo que f(x – 1) = 2x + 3, calcule: a) f(1) b) f(3) *
0 pontos
a) f(1)=7 e f(3)=11
b) f(1)=5 e f(3)=11
c) f(1)=7 e f(3)=8
d) f(1)=5 e f(3)=-11
e) f(1)=7 e f(3)=11

Answer 1

a) f(x – 1) = 2x + 3

f(2– 1) = 2.2 + 3

f( 1 ) = 7

b) f(x – 1) = 2x + 3

f(4 - 1 ) = 2.4 +3

f( 3 ) = 11

=> a) e e) f(1)=7 e f(3)=11
