Question

Can someone help me and show me step-by-step work on how to solve this I will fan and medal!

Graph the function


y=-x^2-2

Answer 1

Ok so you would start by graphing a regular x^2 parabola

Then because there is a "-2" you would shift that graph down 2
And that would be your answer

Answer 2

Or you could just look at it like this

Start with 0 and substitute that for x, you get y=-2 so the point would be (0,-2)

Repeat with as many numbers as you want, for example if you substitute 1 for x you would get (1,-1)

Answer 3

I know how to do that but my teacher said I have to show how I get the vertex and the y intercept and stuff
