Question

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

Answer 1

Are you able to graph the two functions and look at them for yourself?

Answer 2

@milk_cart0n

Answer 3

that would help.. the difference is the constant -5, in any graph a constant shifts the graph in the y-axis

Answer 4

I don't understand how to graph them, but thank you

Answer 5

Thank you, as in lucaz explained it to you? lol

Answer 6

Differences:
- The graph y2 = -2x^2 passes at the origin O. The graph y1 = -2x^2 - 5 passes at point (0, -5)
- The graph y2 has double x-intercepts (double real roots) at point origin (0, 0). The graph y1 doesn't have x-intercepts (no real roots, or 2 complex roots)
- y2 has its max at (0, 0). y1has its max at (0, -5)
