Question 272408
the general equation for the axis of symmetry is ___ x = -b / 2a
___ in this case ___ x = -(-2) / (2 (1)) = 1


the domain is the "allowable" values for x ___ ones that don't cause undefined y values (like division by zero)
___ in this case, x can be any real value


the range is values for y resulting from x values put through the function
___ this is a quadratic (parabola)
___ it opens upward (the coefficient of the square term is positive) and has a minimum value (on the axis of symmetry)
___ this minimum value is the lower boundry for the range ___ there is no upper boundry
