What material is this from?

anonymous · Answer

Algebra 2/trig

anonymous · Answer

In their notation is "a" the horizontal shift, "b" the vertical shift, and "k" the vertical scaling?

anonymous · Answer

i have no idea..
i have to do it online and i couldn't understand the material very well and i meet with my math tutor next wednesday but i have to have it done..

anonymous · Answer

So for example the parent function y=x
y=k(x-b)+a?

The problem is those variable names are arbitrary it could also be

y=a(x-k)+b etc.

Is there an example in your text that shows their usage?

anonymous · Answer

nope its all online.. thats all that it gave me

ganeshie8 · Answer

check in ur online lessons page,   if u have some equation like below  :-

$\large f(x) = b\sqrt{ax} + k$

ganeshie8 · Answer

which online school u doing ?  flvs/vlacs/connexus/others ?

anonymous · Answer

$$y=2\sqrt{2x+3}$$
or$$y=2\sqrt{2x}+3$$

anonymous · Answer

I'm doing advanced academics

anonymous · Answer

ok so what would this be?

For the parent function y equals the cube root of x, what effect does the values h = -4 have on the graph?
	A.	Horizontal shift of 4 units to the right
	B.	Horizontal shift of 4 units to the left
	C.	Vertical shift of 4 units up
	D.	Vertical shift of 4 units down

anonymous · Answer

I don't know the conventions that your course uses for "h".
I can't believe that it wouldn't be listed for you somewhere in your material.

anonymous · Answer

it would be D right?

ganeshie8 · Answer

h usually refers to horizontal shift.
again we need to know wat they refer to as h, it will be there in ur lessons page im sure :)

anonymous · Answer

yayyy thanks! i got a 70% but i got all the ones right that you guys gave me!! thank you!!!!!

ganeshie8 · Answer
