How is the graph of y = 5x2 - 4 different from the graph of y = 5x2?

Answer:first equation is 4 units shifted down from the second

The graph of y = 5x²-4 differs from the graph of y = 5x² by difference of 4 units

Step-by-step explanation:

In y = 5x²-4, when y is 0 x is not 0 and when x is 0, y is not 0

but

In y = 5x², when y is 0, x is 0 and vise versa.

In y = 5x² the value of y will always increase as the value of x increase.
