Would the graph for f(x) = - 9x² + x + 5 open up or down,

Would the graph for f(x) = - 9x² + x + 5 open up or down, and why?, find g(). Down, because a (the coefficient of 2) is negative. Up, because b (the coefficient of x) is positive. Down, because b (the coefficient of a) is positive. Up, because a (the coefficient of 2) is negative.
