i have got this information on a assigment:

f(x) = ln 2x,g(x) = cos(x- p / 2) , a (x) = 2x+ |x- 2 | ,

and the question is to draw the curve ofy=f(|1-x|)

i think it will then bey=f (|1-ln2x|) right ?

*f*(*x*) = ln 2*x*,*g*(*x*) = cos(*x*- p / 2) , a (*x*) = 2*x*+ |*x*- 2 | ,

and the question is to draw the curve of*y*=*f*(|1-*x*|)

i think it will then be*y*=*f (|*1-ln2x|) right ?

okej.

f(|1-x|)=ln[2(|1-x|)] is it the same as y=ln[2(|1-x|)]

If you're familiar with ln(x) you could also do it this way.

Has a vertical asymptote at x=0 and f(x) = 0 at x = 1.

makes the function even and symmetric about the y-axis.

Reflect the graph about the y-axis.

Shift the graph 1 unit to the right.

Shift the graph up ln2 units.
