The graph above represents the function $y = -3x^2$, and the table below shows some sample points from the function:

$x$	$y = -3x^2$
-10.0	-300.0
-9.80	-288.00
-9.60	-276.25
-9.39	-264.74
-9.19	-253.47
-8.99	-242.45
-8.79	-231.68
-8.59	-221.15
-8.38	-210.87
-8.18	-200.83

Do you need further details or have any questions?

Here are five related questions for further practice:

1. How does changing the coefficient of $x^2$ affect the shape of the parabola?
2. What is the vertex of the parabola for $y = -3x^2$?
3. Can you determine the axis of symmetry for this parabola?
4. How would the graph change if the equation was $y = 3x^2$?
5. What happens to the value of $y$ as $x$ approaches infinity?

Tip: The coefficient of $x^2$ determines whether the parabola opens upwards (positive) or downwards (negative).
