a) f(0)

b) 1(1)

C) f(2)

d) f(3)

e) f(-1)

f) f(15)=21

7. Dado fix) = x + 7x + 10, calcule

a) f(0)

b) f(1)

c) f(2)

d) f(-1)

e) f(-3)

f) f(-5)

8. Sendo fx) = x +4, f:R→R. calcule x
para que se tenha:

a) f(x)=0

b) f(x)=5

c) f(x)=12

d) f(x)=21​

Answer 1

Resposta:

7) f(×)=,x+7×+10

f(0)=0+0+10

f(0)=10

f(1)=++7+10

f(1)=27

f(2)=2+14+10

f(2)26

f(-1)= -1-7+10

f(-1) =2

f(-3)= -3-21+10

f(-3)=-14

f(-5)= -5 -35+10

f(-5) = -30
