dude · Answer

Simply substitute -2.3 in for x in the equation for $g(x)=2[x]-1$

I would but I don't get how to do that either that's why I asked online cause I cant do it. I want the answer not how to do it cause I don't know how, that's why i put the possible answers.

dude · Answer

Is the bracket confusing you?

Hero · Answer

$g(-2.3) = 2[-2.3]-1$ are you able to at least calculate that @looollzz

looollzz · Answer

No im stupid i dont get it

dude · Answer

Ah you're completely lost?

looollzz · Answer

yes.

dude · Answer

We know that $g(x) = 2[x] − 1$ is the equation for a function named g(x)

$g(x)$ can also mean y
So you can rewrite it as $y=2[x]-1$ if that is clearer
