Question

Dada a função f(x)=x²-5x+6, calcule:
a) A(-1)
b) f(0)
c) ƒ(1)
d) f(2)​

Answer 1

Explicação passo-a-passo:

a) Se for f(-1)

f(-1)= (-1)² - 5.(-1) +6

f(-1)= 1 +5 +6

f(-1)= 12

b) f(0)= 0² - 5.0 +6

f(0)= 0 - 0 +6

f(0)= 6

c) f(1)= 1² - 5.1 +6

f(1)= 1 - 5 +6

f(1)= -4 +6

f(1)= 2

d) f(2)= 2² - 5.2 +6

f(2)= 4 - 10 +6

f(2)= - 6 +6

f(2)=0
