Question

If you answer this I will send a thanks.

But I can't send a thanks if you don't explain it step by step. ASAP

Answer 1

Is that supposed to be

`f(x) = x \cdot |-1|^x`

?

Let's assume so. This is really bad computer aided instruction if they can't typeset simple formulas in a way that doesn't look like it was written by a drunk. Tell your school to get a better system than this; you deserve better.

`f(2) = 2 \cdot |-1|^2 = 2 \cdot 1^2 = 2\cdot 1 = 2`

Answer: 2, last choice
