Given a = 2, b = -2 and k = 3, what is the equation of the graph if the parent function is y= /-x?

Question

surana · Answer

Technically, it's $$y=\sqrt{x}$$

@bohotness , @misty1212

bohotness · Answer

do you know how to do tha/T

surana · Answer

Sort of, I need help with things like this.

bohotness · Answer

okay

surana · Answer

Yes.

geerky42 · Answer

Exactly what do a, b, and k stand for?

geerky42 · Answer

Is it some sort of transformations?

surana · Answer

a, b and k stand for, respectively, 2, -2 and 3.

geerky42 · Answer

I know, but what do they represent?

geerky42 · Answer

let me guess, a is x-shift and b is y-shift, and k is vertical scale?

As in $k\sqrt{-(x-a)}+b$?

surana · Answer

Variables for the equation.

surana · Answer

That might be it, actually.

geerky42 · Answer

Ok, then just plug in value and you will have your equation, I guess

geerky42 · Answer

I made assumption, so I could be wrong.

surana · Answer

So I put the numbers into the places where the variables themselves are and that's my answer?

geerky42 · Answer

I think so. your question doesn't give enough information for us

surana · Answer

Well, that is the entirety of the question.

surana · Answer

3$$3\sqrt{-x(-2)} + (-2)$$

surana · Answer

So it's basically that?

geerky42 · Answer

$3\sqrt{(-x-2)}-2$

but this is only if general function is $k\sqrt{(-x-a)}+b$

geerky42 · Answer

It depend on where a, b, and k is in general equation. I think you should be given that in maybe previous questions or something?

surana · Answer

I think it follows the general equation.

geerky42 · Answer

well, whether it is, just plug in and simplify if needed, and you are good.

geerky42 · Answer

couldn't  be much help, sorry

surana · Answer

It's alright. thank you.
