Question 200152
I'll do the first three values to get you started....



x = -2:



{{{y=x^2-x-2}}} Start with the given equation.



{{{y=(-2)^2--2-2}}} Plug in {{{x=-2}}}.



{{{y=(-2)^2+2-2}}} Simplify.



{{{y=4+2-2}}} Square {{{-2}}} to get {{{4}}}.



{{{y=4}}} Combine like terms.



------------------------------------------------------------



x = -1:



{{{y=x^2-x-2}}} Start with the given equation.



{{{y=(-1)^2--1-2}}} Plug in {{{x=-1}}}.



{{{y=(-1)^2+1-2}}} Simplify.



{{{y=1+1-2}}} Square {{{-1}}} to get {{{1}}}.



{{{y=0}}} Combine like terms.



------------------------------------------------------------



x = 0:



{{{y=x^2-x-2}}} Start with the given equation.



{{{y=(0)^2-0-2}}} Plug in {{{x=0}}}.



{{{y=0-0-2}}} Square {{{0}}} to get {{{0}}}.



{{{y=-2}}} Combine like terms.
