Answer 1

Hey! (｡❀´∀｀)ﾉ

Oh my god, I HATED learning about solving equations with absolute values...but the ones they taught me were harder than this, they actually had equations inside the absolute value. (❀>_<) Anyways, sorry for babling, I am going to try to help. (❀°∀°)b So, I think if they say they are looking for the output of "f(2), then you have to change the x-values to 2. So the new equation would be...

\[f(2)=2 \times \left| -1 \right| ^2 \]

Now, the first thing here is to find out what the absolute value of -1 is. Do you know? :-)

um 1?
