Answer 1

y =
$- {x}^{2}$
Com 0: y =
$- {0}^{2}$
$0$
Com 1: y =
$- {1}^{2}$
$- 1$
Com -2: y =
$- ( - 2) {}^{2}$
$- 4$
Com 3: y =
$- {3}^{2}$
$- 9$
Com -4: y =
$- ( - 4) {}^{2}$
$- 16$

y =
${x}^{2} - 1$
Com 0: y =
${0}^{2} - 1$
$- 1$
Com 1: y =
${1}^{2} - 1$
$0$
Com -2: y =
${(-2)}^{2} - 1$
$3$
Com 3: y =
${3}^{2} - 1$
$8$
Com -4: y =
${(-4)}^{2} - 1$
$15$

y =
-x² + 2x
Com 0:
-(0)² + 2 × 0
y = 0
Com 1:
-(1)² + 2 × 1
y = 1
Com -2:
-(-2)² + 2×(-2)
y = -8
Com 3:
-(3)² + 2 × 3
y = 15
Com -4:
-(-4)² + 2 × (-4)
y = -24

y =
x² - x - 6
Com 0:
0² - 0 - 6
y = -6
Com 1:
1² - 1 - 6
y = -6
Com -2:
(-2)² -(-2) -6
y = 0
Com 3:
3² -3 -6
y = 0
Com -4:
(-4)² -(-4) -6
y = 14

y =
-x² + 2x + 8
Com 0:
-(0)² + 2 × 0 + 8
y = 8
Com 1:
-(1)² + 2 × 1 + 8
y = 9
Com -2:
-(-2)² + 2 × (-2) + 8
y = 0
Com 3:
-(3)² + 2 × 3 + 8
y = 5
Com 4:
-(4)² + 2 × 4 + 8
y = 0

y =
x² - 6x + 5
Com 0:
0² - 6 × 0 + 5
y = 5
Com 1:
1² -6 × 1 + 5
y = 0
Com -2:
(-2)² -6 × (-2) + 5
y = 21
Com 3:
3² -6 × 3 + 5
y = -4
Com -4:
(-4)² -6 × (-4) + 5
y = 45
