How is the graph of y=-2x^2-5 different than the graph of y=-2x^2

Answer 1

The graph of y=-2x^2-5 is the same as the graph of y=-2x^2 shifted downward 5 units. This means that while both graphs have the same shape (a downward facing parabola), the graph of y=-2x^2-5 is lower and intersects the y-axis at y=-5.
