Answer 1

$y = {x}^{2} + x + 1$

$x = - 3$

$y = ( - 3) {}^{2} + ( - 3) + 1 = 9 -3 + 1 = 10 - 3 = 7$

$x = - 2$

$y = ( - 2) {}^{2} + ( - 2) + 1 = 4 - 2 + 1 = 5 - 2 = 3$

$x = - 1$

$y = ( - 1) {}^{2} + ( - 1) + 1 = 1 - 1 + 1 = 1$

$x = 0$

$y = 0 {}^{2} + 0+ 1 = 1$

$x = 1$

$y = {1}^{2} + 1 + 1 = 1 + 2 = 3$

$x = 2$

$y = 2 {}^{2} + 2 + 1 = 4 + 3 = 7$

$x = 4$

$y = {4}^{2} + 4 + 1 = 16 + 5 = 21$

$x = 7$

$y = 7 {}^{2} + 7 + 1 = 49 + 8 = 57$
