Question 1042471
The y-coordinate of the vertex is {{{y=-6}}} .
Since the parabola opens up, for all the points in the graph, {{{y>=-6}}} .
So, you could say that the range is
all the real numbers greater than or equal to {{{-6}}} ,
or in interval notation {{{"[ - 6 ,"}}}{{{infinity}}}{{{")"}}} .
The domain of any quadratic function is all the real numbers.
