Question

(1) $y=x^{2}+6x+7$
$=(x+3)^{2}-2$
$=(-3,-2)$
fill in the following table:

$x$$y$--------$-6$$-5$$-4$$-3$$-2$$-1$$0$

Explanation:

Step1: Substitute $x=-6$

$y=(-6)^2+6(-6)+7=36-36+7=7$

Step2: Substitute $x=-5$

$y=(-5)^2+6(-5)+7=25-30+7=2$

Step3: Substitute $x=-4$

$y=(-4)^2+6(-4)+7=16-24+7=-1$

Step4: Substitute $x=-3$

$y=(-3)^2+6(-3)+7=9-18+7=-2$

Step5: Substitute $x=-2$

$y=(-2)^2+6(-2)+7=4-12+7=-1$

Step6: Substitute $x=-1$

$y=(-1)^2+6(-1)+7=1-6+7=2$

Step7: Substitute $x=0$

$y=(0)^2+6(0)+7=0+0+7=7$

Answer:

$x$$y$
$-5$$2$
$-4$$-1$
$-3$$-2$
$-2$$-1$
$-1$$2$
$0$$7$
