The replacement set is 

Replace x in with each value in the replacement set and

check whether the equation is true or not. \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\ x \	\ \	\ Y = ? \
\ -2 \	\ \	\ y = - 5.75 \
\ -1 \	\ \	\ y = - 2.50 \
\ 0 \	\ \	\ y = 0.75 \
\ 1 \	\ \	\ y = 4.00 \
\ 2 \	\ \	\ y = 7.25 \

\

Since y = {- 5.75, - 2.50, 0.75, 4.00, 7.25}

 The solution set is y = {- 5.75, - 2.50, 0.75, 4.00, 7.25}.
