1. ## graphs absolute

Say you have f(x) = x

so it looks like this /

if you do f(|x|)... will it make it look like V or <

THANKS

V.

3. IT cannot look like <
Because otherwise it is not a function (vertical line test).

4. Just reflect all the -xs about the x axis and you'll get V

Here's the graph.

6. Hello, Mr_Green!

Say you have $f(x) = x$

so it looks like this: /

If you do $f(|x|)$ . . . will it make it look like $\lor$ or $<$ ?

Since we have $f(x) = |x|$, the graph is symmetric to the y-axis: . $\lor$
