Compare the graphs of each group of functions and list them in order from widest to narrowest:

y = -3x², y = -5x², y = -1x^2.

• y = -5x²

• y = -1x²

• y = -3x²

Compare the graphs of each group of functions and list them in order from widest to narrowest:

y = 4x², y = -2x², y = -6x^2.

• y = 4x²

• y = -6x²

• y = -2x²

Determine whether the graph of the function y = -6x² opens upward or downward.

• Upward

• Downward

• Neither
