apply the quadratic formula to find the roots of the given function, and then graph the function.
f(x) = x^2 + 4
X=+i....OR......-i
X..........0...............1..............2........ETC
Y..........0...............5..............8.........ETC
g(x) = x^2 + x + 12
X=-0.5+i*0.5*SQRT(47)............OR..........-0.5-i*0.5*SQRT(47)
X..0..........1.........2.......ETC
Y..12.........14........18.ETC
