Im having trouble creating the function table for the Quadratic function: y=x^2 + 2x + 4
When I input x as -1 , y is 1,
But when I input x as 1, y is 5
BUT , it comes out fine when x = 2 or -2 !
x=-2 --> y=-4
x=2 --> y=4
What am I doing wrong !??

When x = - 1, y = (-1)^2 + 2* (-1) + 4 = 1 -2 +4 = 3.
When x = 1 , y = 1 + 2 + 4 = 7.
Just be more careful with your substitutions and remember that (-a)^2 = a^2

Actually, when x is a 1, y is a 3, and when x is a 1, y is 7.
