Can someone help me with this question?

Here's the graph, here......https://www.desmos.com/calculator/vox1ksffz0

Notice that Melody is correct.....the graph is > 0 at x < - 1 and x > 3

I just answered one of them for you.

x=3 or x=-1

$$y=x^2-2x-3$$

is a concave up parabola

so y will be greater than 0 at the ends that is

x<-1 and x>3
