For the parent function y= square root x , what effect does a value of k = -3 have on the graph? A. Horizontal shift of 3 units to the right B. Horizontal shift of 3 units to the left C. Vertical shift of 3 units up D. Vertical shift of 3 units down
\[f(x)=\sqrt x\] Where do you see a k
after the square root right?
I think the point is that you are asking what effect a certain k value will have on the graph and no one has any idea because there is no k in the equation.
Is this the form we're suppose to use perhaps? \[\large f(x)=\sqrt{x-h}+k\] Which would shift the vertex of the parabola to \(\large (h,k)\).
Head... still.. asleeps =_=
@zepdrix you're almost as bad as I am. lol
Blah not parabola, but the idea still holds. It would shift the..... base point? or whatever.. of the root over to \(\large (h,k)\)
The K is shifting the function UP or DOWN. Since it's negative, it will shift it downward. Yah... something like that -_-
Yea, K shifts it vertically and H shifts it horizontally.
