Answer 1

y-intercept: (0,19)

The y-intercept of an equation is the point where the graph of the equation crosses the y-axis. In this case, when x = 0, the equation simplifies to y = 19, so the y-intercept of the graph is (0, 19).

The coefficient of the x² term is 0.9, which is positive, so the parabola opens upwards.

So the answer is

Parabola opens upward.
