What is the range to g(x)=25-x^2

Question

I was wondering what was the answer to g(x)=25-x^2

I was confused by my answer choicer Wich are

1.) X≤25

2). -5≤x≤5

3.) -5≤g(x)≤5

4.) G(x)≤25

I was confused because I know that x is for the domain of you could please help me understand what I am not getting that would help and tell me what the range is .

Answer 1

Range is possible values of g(x)

x² >= 0 for all x

-x² <= 0 for all x

25-x² <= 25 for all x

So range is g(x) <= 25
