You can put this solution on YOUR website!
y=x%5E2%2B2 Start with the given equation
y=1%28-2%29%5E2%2B2 Plug in x=-2
y=1%284%29%2B2 Square -2
y=4%2B2 Multiply
y=6 Add


So we have the point (-2,6)

-------------------------------------------------
y=x%5E2%2B2 Start with the given equation
y=1%28-1%29%5E2%2B2 Plug in x=-1
y=1%281%29%2B2 Square -1
y=1%2B2 Multiply
y=3 Add


So we have the point (-1,3)

-------------------------------------------------
y=x%5E2%2B2 Start with the given equation
y=1%280%29%5E2%2B2 Plug in x=0
y=1%280%29%2B2 Square 0
y=0%2B2 Multiply
y=2 Add


So we have the point (0,2)

-------------------------------------------------
y=x%5E2%2B2 Start with the given equation
y=1%281%29%5E2%2B2 Plug in x=1
y=1%281%29%2B2 Square 1
y=1%2B2 Multiply
y=3 Add


So we have the point (1,3)

-------------------------------------------------
y=x%5E2%2B2 Start with the given equation
y=1%282%29%5E2%2B2 Plug in x=2
y=1%284%29%2B2 Square 2
y=4%2B2 Multiply
y=6 Add


So we have the point (2,6)

Now plot the points

Now connect the points, this is the graph of y=x%5E2%2B2
