Question

Dada a funcao f(x) =x²-5x+6 determine
A) f(-1)
B)f(0)
C) f(3)
D) f(-3)

Answer 1

Resposta:

a)f(-1)=12

b)f(0)=6

c)f(3)=0

d)f(-3)=30

Explicação passo-a-passo:

a)f(-1)

f(-1)=(-1)²-5•(-1)+6

f(-1)=1+5+6

f(-1)=1+11

f(-1)=12

b)f(0)

f(0)=0²-5•0+6

f(0)=0-0+6

f(0)=0+6

f(0)=6

c)f(3)

f(3)=3²-5•3+6

f(3)=9-15+6

f(3)=9-9

f(3)=0

d)f(-3)

f(-3)=(-3)²-5•(-3)+6

f(-3)=9+15+6

f(-3)=9+21

f(-3)=30

f
