Question 177110
find the corresponding y values for x = -4,-3,-2,-1,0,1,2 if y=x2+2r-3.



The equation you give must contain an error. I am guessing that it should be:
y=x^2+2x-3


In any case, you need to solve for y by substituting the different values of x into the equation and solving for y. 

For the first one, if x = -4:
y=(-4)^2+2(-4)-3
y=16-8-3
y=5

and then put 5 across from -4 in the column.
