Question

Hello, I'm in Algebra II
My question is how do I graph y= | 1/2x| -3. The other question is how do I graph y< - | x-4| + 1. The last question that I have a problem with is: Given the graph of y= F(x), use the graph transformations to draw the graph of y= -f (2x)-4.. I could send the graph to you if that is what you need to answer the question. I really having trouble with this.

Answer 1

first answer!! do you know how to graph y =|1/3 x|??

Answer 2

I have an idea but I'm not sure.

Answer 3

just do, show me your work

Answer 4

and it is 1/2x sorry

Answer 5

ok, let me guide you.
first off, draw y =\(\dfrac{x}{2}\) by 2 points (0,0) and (1,1/2)
got me so far?

Answer 6

arbitrary let x =0, then plug into y = 1/2 x to get y =1/2*0 =0 , that's how I get (0,0)

Answer 7

do the same with letting x =1, then plug into y =1/2 x to get y =1/2*1 =1/2 , that's how I get (1,1/2)

Answer 8

What about the negative three?

Answer 9

be patient!!

Answer 10

that's just y = 1/2 x,
now y = |1/2x| , the | | means you take the positive part for y only. Get it by flipping the negative part through x-axis. I mean
