Question

a ) f ( 0 )

b ) f ( 1 )

C) f ( - 1 )

d ) f ( - 5 ) ​

Answer 1

Resposta:

Explicação passo-a-passo:

f(x)=x²-3x+2

a)

f(0)=0²-3.0+2=2

b)

f(1)=1²-3.1+2=1-3+2=0

c)

f(-1)=(-1)²-3(-1)+2=1+3+2=6

d)

f(-5)=(-5)²-3(-5)+2=25+15+2=42

Answer 2

f(x) = x² - 3x + 2

a ) f ( 0 )

0² - 3 • 0 + 2

0 - 0 + 2

2

b ) f ( 1 )

1² - 3 • 1 + 2

1 - 3 + 2

- 2 + 2

0

C) f ( - 1 )

(- 1)² - 3 • ( - 1) + 2

1 + 3 + 2

4 + 2

6

d ) f ( - 5 )

(-5)² - 3 • ( - 5) + 2

25 + 15 + 2

40 + 2

42
