The best way to solve this is to make it a function. f(x)= x^2 +2x +8 Plug in values of x from -3 to 3 and solve ordered pairs to graph. -3^2 +2(-3) +8 -2^2 +2(-2) +8 9 +-6 +8 4 +-4 +8 3+8 (-2,8) 11 (-3,11) Graph the remaining points and your solution will be right in front of you. Graph those two points and you can tell that it opens up.
